At MeteoExpo 2025 in Vienna, Jan Barani presented one of the most talked-about sessions at the Technology & Innovation Theatre — challenging the very foundations of today’s hydrometeorological measurement industry.

Our presentation, “Transparency Starts at the Sensor,” asks a simple but uncomfortable question:

How can we expect the world to trust our forecasts and climate warnings if the instruments we use to collect the data can’t be trusted themselves?

For too long, our industry has hidden behind laboratory certificates and “WMO-certified” marketing claims, while the quality of field measurements has quietly eroded.
From 3 °C temperature errors in official records to low-sampling ultrasonic anemometers that miss entire wind gusts, the credibility gap between data sheets and real-world truth is widening fastMET25_Technology & Innovation T…MET25_Technology & Innovation T….

Fix the Instruments, Not Just the Models

The presentation exposed how:

• “All-in-one” weather sensors combine incompatible measurements that disturb the very air they’re trying to measureMET25_Technology & Innovation T….

• Fan-aspirated radiation shields (FARS) distort measurement height and introduce thermal noise instead of removing itMET25_Technology & Innovation T….

• Low-power ultrasonics with 1 Hz or slower sampling rates can’t capture a 3-second gust and yet are still accepted in automatic weather stationsMET25_Technology & Innovation T….

• WMO’s own time-constant guidelines omit wind-speed context entirely, making the term meaningless in practical meteorologyMET25_Technology & Innovation T….

Rebuilding Credibility

If we want people to trust early warnings again, we must start with transparent instrumentation and open intercomparison testing.
The talk proposes a simple path forward:

• Proposal to implement Continuous WMO intercomparisons open to all manufacturers, funded by HMEI fees— not invite-only.

• Proposal to implement a wind-invariant constant and dimensionless response index to make temperature-sensor performance directly comparable across airspeeds.

• A call for “WMO certification through transparency”, where every sensor is verified in field conditions, not just in a chamber of a calibration laboratory.

What does the future hold for the MeteoRain family of pluviometers

These long-awaited advances in the MeteoRain family, while taking 3 years longer than initially anticipated, have produced a highly reliable and precise measurement instrument that has been field-tested worldwide in all climates. Based on customer feedback, MeeteoRain 200 Pro rain gauges are slowly replacing all of our competitors’ tipping buckets and siphoning rain gauges in the professional segment. Notably, BARANI offers an affordable upgrade to its customers interested in upgrading their MeteoRain 200 Compact rain gauges to the new Pro version.

This update allowed BARANI to finally start work on the MeteoRain 400 Pro, which will be offered in 4 flavors:

1. An affordable Upgrade to the MeteoRain 200 Pro will increase the catchment area to 400 cm2 and double the resolution to 0.1 mm of rain.

2. The stand-alone MeteoRain 400 Pro is a complete product, including a wind fence, bird spikes, and leaf fence, all with 0.1 mm resolution.

3. Wireless MeteoRain 400 IoT Pro adds an internal battery and hidden antenna to the MeteoRain 400 Pro.

4. The Heated MeteoRain 400 Pro will feature a high-efficiency heater, making use of solar power in remote locations possible.

   • A wireless version of the Heated MeteoRain 400 Pro is also a possibility, depending on professional customer demand.

This unique technological combination in the MeteoHelix has become the building block technology enabling climatological networks to meet strict WMO measurement standards affordably. An unexpected side benefit of this adoption has been the staggering growth rates of these networks, some of which are more than doubling in size each year. One of the fastest-growing networks is located in Belgium, which has recently become the country with the most densely populated WMO-compliant weather stations per square kilometer.

The year 2022 brings improvements to the MeteoHelix IoT Pro based on input from researchers in Antarctica and the Death Valley and feedback from many other climates. This guarantees pure measurement accuracy and data quality not based on data corrections and black-box artificial intelligence algorithms to compensate for low-quality meteorological measurements. The MeteoHelix IoT Pro provides uniform data quality in all climates ranging from the snow-covered planes of Antarctica to the rain forests of Indonesia and the sun-soaked deserts of the Death Valley.

This month in Chicago, BARANI DESIGN Technologies will be exhibiting and looking for B2B partnerships for the USA, Canada, and Mexico markets at the Meteorological Technology World Expo North America. This B2B expo will be at the Stephens Convention Center in Chicago on August 31 and September 1, 2022.

Measurement consistency, compact size, and its ability to measure even when not wholly level make the MeteoRain 200 Compact rain gauge a favorite for watershed monitoring, agriculture, and smart-city installations. Also available in a wireless version, this compact rain gauge not only features a standardized 200 cm2 measuring orifice area to WMO standards but does this in a very compact package whose installation is limited to just four screws.

Featuring a self-balancing, highly vibration-resistant measuring mechanism, it can provide consistent data quality for years on end. Additionally, long-term maintenance-free operation requires only a single re-calibration within 6-12 months of installation to account for soiling, after which it can operate with minimal measurement uncertainty for years.

Sometimes the best gets better, which is the case with the only helical solar radiation shield for weather station temperature sensors. Listening to feedback from its customers in Antarctica, the Death Valley, and the Sahara, BARANI DESIGN Technologies has brought the last few remaining improvements to the already class-leading helical MeteoShield® Professional.

This new 3rd generation (Gen 3) naturally ventilated solar radiation shield features improved reflected light control from snow-covered or solar-heated ground while maintaining the high air flow rates, which is the number one factor guaranteeing measurement quality. Additionally, solar-powered artificial fan ventilation is available for the rare, less than 0.5 m/s (1.1mph) wind conditions, where all naturally ventilated solar shields show some signs of solar heating.

While these improvements may seem subtle to the naked eye, their combined effect reduces the already class-leading measurement uncertainty in all weather conditions to below 0.1°C, far below even many fan-ventilated solar screen counterparts.

While NB-IoT has its advantages, the low-cost of LoRaWAN gateways may significantly stun its growth, especially in meteorological and agricultural sensor applications.

The advantage of NB-IoT stemmed from the apparent fact that NB-IoT sensors operate in a licensed radio frequency band with lower radio noise pollution than the free radio frequency bands of LoRaWAN or Sigfox devices. Yet this potential data transmission reliability advantage is discounted by LoRa’s higher sensitivity, higher resistance to interference, and by low RF noise levels in non-metropolitan areas. NB-IoT’s use of licensed frequency bands adds ceiling-less recurring data subscription charges for each deployed sensor.

Additionally, NB-IoT sensors and devices use UDP data transfer protocol which does not guarantee data delivery to the server or data security like SFTP or HTTPS protocols do. All these factors level the playing field and may give the upper hand to LoRaWAN sensors and devices in terms of sensor data delivery reliability and in mission-critical applications.

Total cost advantage of LoRaWAN

With the latest generation of LoRaWAN gateways available for sub $100 USD and the added affordability of running one’s own LoRaWAN server through providers like The Things Industries, the case is clear for LoRaWAN in terms of affordable wide-area wireless sensor networks as required for agriculture and environmental research. Lower cost of LoRaWAN gateways, advantages of LoRaWAN’s star-on-star network topology, and simple gateway deployment scenario minimize upfront investment together, and most of all, minimize recurring data subscription charges.

It is important to understand that gateways that support and operate on the LoRaWAN LoRa Basics™ Station protocol offer superior reliability in terms of data delivery reliability. While the LoRa Basics™ Station protocol consumes more bandwidth on a Wifi, Ethernet or LTE data connection, it operates on the HTTPS protocol to guarantee data security and reliability that UDP cannot.

Opportunity where LTE and NB-IoT coverage ends

For areas on the edge of 3G/4G/LTE/NB-IoT coverage which are commonly found in agricultural applications, simple and highly affordable plug-&-play LoRaWAN solutions combining LTE modems with LoRaWAN gateways offer hard to beat sensor network solutions for weak wireless coverage areas. As an example, the solution offered by BARANI DESIGN Technologies for professional WMO quality environmental monitoring in Africa, USA, Canada, Mexico, Asia, Australia, and South America combines a preconfigured TTIF LoRaWAN Femto gateway or a Wifx Lorix One outdoor gateway with either a MIKROTIK RouterBOARD wAP LTE kit or a MIKROTIK RouterBOARD SXT LTE6 kit.

While the BARANI DESIGN Technologies wireless agricultural weather stations are seeing record installations in 2020, we have been hard at work to finalize the latest addition to our modular agricultural weather station sensor set.

Along side soil water tension sensors, soil water content sensors and soil temperature sensors, the MeteoAG wireless agricultural node will also provide critical leaf wetness data along with near surface air temperature data essential to monitoring late autumn and spring frost events.

The final testing phase of MeteoAG has started and will continue throughout December and over the Christmas holidays in preparation for the start of the 2021 farming season.

For the first time in history, on September 24, 2020, exact amounts of rainfall started being recorded on its summit by a BARANI DESIGN Technologies MeteoHelix weather station together with a new MeteoRain 200 Compact rain gauge. The compactness of these WMO precision instruments and ease of their installation enabled local mountain guides to install this weather station in a location that was inaccessible to weather station equipment even just 2 years ago. Able to survive and transmit weather data even from under large snow cover for up to 4 months, the highly survivable MeteoHelix weather stations are ideally suited for environmental research in hard to access locations.

An additional fact worth noting is the ability of the MeteoRain 200 Compact to measure rain even in below freezing temperatures as show in the plot below. Detailed live meteorological data from Gerlachov Peak can be found through the following link:

SensCity, one of the pioneers of Smart-City and Resilient-City climate monitoring has chosen to work with the highest quality urban climate monitoring sensors the market has to offer. Choosing to install the BARANI DESIGN MeteoHelix IoT Pro, MeteoWind IoT Pro and MeteoRain sensors for urban climate monitoring in Stockholm, Sweden on street lamps was by no means a coincidence.

Based on World Meteorological Organization (WMO) verified technologies in combination with IoT wireless data transmission, these sensors not only offer the highest levels of precision but also unparalleled ease of installation. Being solar powered and requiring no wires to connect, their installations on busy urban streets are quick and thus cost-effective.

Other sensors in use by SensCity include the MeteoAG which offers the expanded capability for agricultural monitoring of soil moisture, soil temperature, and leaf wetness.

The 1st in a line of new precipitation sensors, the MeteoRain 200 Compact rain gauge, begins production testing. Early independent testing has shown it to far outclass any other tipping bucket rain gauge in terms of accuracy and repeatability of measurement in field operations, thus classifying it as a maintenance-free meteorological sensor suitable for mass deployments.

As MeteoRain 200 Compact early production batch nears completion, preorder customers will be first in line to receive their units. The MeteoRain line of rain gauges features the only ultra-low-power rain gauges capable of high-precision rain measurement without regular maintenance.

MeteoRain 200 Compact is the first in line and will soon be followed by the stand-alone wireless MeteoRain IoT Compact and MeteoRain 400 Pro. They are designed for mass sensor deployments in Smart Cities, agriculture, and due to their high accuracy and repeatability of measurement can be used to replace aging WMO and NWS compliant meteorological equipment.

The University of Reading, in a project called the “Rainfall Rescue” by Prof. Ed Hawkins, is crowdsourcing help from people stuck at home due to the coronavirus COVID-19 outbreak. The goal is to help transcribe old written records that are missing in the UK digital weather database between the years 1820 and 1950.

The effort is open to the public. Join here to help: https://www.zooniverse.org/projects/edh/rainfall-rescue

The digitized data allow scientists to analyze climatic changes better and to help them differentiate between short-term, medium-term, and long-term fluctuations in weather patterns.

In an effort to bring WMO quality rain and climatic measurement to the masses, BARANI DESIGN Technologies has developed a series of Internet-of-Things (IoT) micro-weather station sensors that are affordable enough for most households. More information can be found at the following links:

QUESTION: How far away do I need to stay from people without a mask so that I don’t breath in what they exhale?

ANSWER: This video shows the movement of breath from person to person during a conversation between two people. There is a very low chance of infection since unlike with a cough or a sneeze, cells, water droplets and other particles like bacteria and viruses are not normally present in a person’s breath.

QUESTION: How far does a cough or sneeze travel and how easily can in infect me?

ANSWER: These videos show the expulsion of particulates in a person’s cough and sneeze. Each sneeze or cough launches cells, water droplets, and other particles like virus and bacteria quite a distance into the air which can infect another person. Infection is most likely if the particles are inhaled or deposited on mucus membranes and other sensitive places on another person’s body.

• It is very important for sick and infected people to wear facial masks to protect others from their infection.

• For healthy people, masks are a good precaution to help limit risk of infection.

QUESTION: How big of a chance does a cough or sneeze have of transmitting a virus or bacteria onto another person?

ANSWER: This video makes a less scientific, yet very practical and understandable approach, to explain how easily coughs and sneezes can transmit diseases to people around us.

We at BARANI DESIGN Technologies are also indirectly very affected by the Coronavirus Disease 2019 (COVID-19), just as are all people, families, and businesses. Slowing the pace of infection is the single most important thing that we all can do so that the capacities of our health care systems are able to cope with the critically sick, not only from COVID-19, but also from other serious illnesses which are taking away our loved ones.

When avalanche rescue needs reliable data, only one weather station can send it from under the snow pack with a 12+ km (7.5+ miles) wireless range.

Extreme weather requires tough hardware

In meteorology, the real difference between professional and commercial hardware is not only in measurement accuracy, long-term measurement stability and precision, but also in toughness, robustness and survivability. The fine line between extreme weather and a weather disaster is the damage caused and loss of life. Timely and accurate decisions require accurate and reliable data in the most extreme weather situations. This is what sets apart professional meteorological equipment from the rest and enables the prevention of disasters and loss of life. MeteoHelix IoT Pro weather stations donated to the Slovak Avalanche Service are proving their worth against all existing weather station hardware.

Buried alive under the snow

Buried under wind blown snow pack for over two months at 1727 meters (5669 feet) above sea level, the MeteoHelix kept tirelessly measuring and sending wireless data every 10 minutes to Sigfox gateways installed by SimpleCell and located 12.5 km, 16.5 km, 20 km, and 32,5 km away. The 3+ meter high snow pack here was unexpected in this warmest winter on record.

Over the two months, tons of wind blown snow consolidated and with a crushing force devastated other meteorological equipment. Under this force, the stainless steel mounting bracket holding the MeteoHelix was bent over like a sheet of paper as shown in the accompanying photo. The MeteoHelix survived without damage. After being dug out and over the next two days as temperatures rose above freezing, the snow packed around its sensors from the burial thawed. The MeteoHelix IoT Pro returned to measuring atmospheric temperatures (instead of snow pack temperature) for which it was designed and which it preforms better and more accurately than any other professional meteorological weather station due to its special patented helical solar radiation shield design.

• Extend wireless network coverage 10+ km past existing LTE, GSM, NB-IoT, CAT-M1 coverage with LoRaWAN LTE gateways

• LoRaWAN gateway affordability ensures deployment of double and triple-redundant wireless networks affordably due to its Star-on-Star approach vs. mesh networking.

• Meteorological sensor nodes communicate with multiple gateways, ensuring reliability of wireless data transmission and interference resistance. In case of a gateway failure, data is automatically rerouted via other gateways.

• LoRaWAN networks allow the addition of unlimited nodes without rebuilding the wireless infrastructure.

• LoRaWAN networks naturally permit network expansion and do not require trained personnel in the field to support network operation since gateways act as only message forwarders (data pass-through) and sensor nodes do not join/pair with gateways, but directly with the application running at the Met Department.

WMO Precision Wireless LoRaWAN Meteorological Sensors

For meteorological network building to the highest WMO measurement standards.

• MeteoWind® IoT Pro exceeds WMO/NWS standards by 5X, making it maintenance free for a lifetime.

• MeteoHelix® IoT Pro meets WMO/NWS standards and due to its helical shield is maintenance free for 2X longer than any other temperature humidity sensor solution.

• MeteoRain® IoT Compact is designed for high-density deployment and affordability. Its measuring mechanism is more accurate than any other rain gauge under 1000 EURO. Soon to be released MeteoRain® IoT Pro with a larger and taller collector bucket will exceed all WMO and NWS measurement standards.

Data for these tables was acquired from https://www.crunchbase.com.

Wenn Sensornetzwerke nicht dem grundlegenden Messstandards entsprechen, werden Smart-City-Sensornetzwerke zu einem Geldfresser. Sie können großartige Ideen in eine sinnlose Infrastruktur und Wolken von falschen oder bedeutungslosen Daten verwandeln.

Zu Beginn des 21. Jahrhunderts begannen Städte im Rahmen der vierten industriellen Revolution (Industrie 4.0), mit Smart-City-Projekten zu experimentieren, noch bevor der Begriff Internet-of-Things (IoT) populär wurde. Jetzt, auf dem Höhepunkt des durch künstliche Intelligenz und Datenverarbeitung ausgelösten IoT-Hype, werden die ersten Anzeichen für die Notwendigkeit, die grundlegenden Messstandards von  NIST, WMO/CIMO, NWS/NOAA, ASTM und ISO zu treffen, offensichtlich.

Das klarste Beispiel für die Notwendigkeit, grundlegende Messstandards zu treffen, kann man in Überwachung des Stadtklimas finden, da die Städte eine Reihe von Herausforderungen an die genaue Messung der Lufttemperatur stellen. Die Fußwege und Gebäudewände in der Nähe von Wetterstationen reflektieren und strahlen Sonnenenergie viel stärker als Grasrasen und aus jeder Richtung auf einen Temperatursensor ab, was zu großen Fehlern bei der Lufttemperaturmessung führt. Da die Verteilung der Fehler bei der Lufttemperaturmessung nicht symmetrisch rund um tatsächlichen Temperaturwert und für jede Wetterstationsinstallation einzigartig ist, hat die Praxis gezeigt, dass sich die Qualität von Daten geringer Qualität nicht mit der Größe des Datensatzes verbessert.

Die Qualität der Lufttemperaturmessung kann leicht beurteilt werden, indem die Sonneneinstrahlung (W / m²) und die Lufttemperatur (° C / ° F) zusammen eingezeichnet werden. Lufttemperatursensoren niedriger Qualität zeigen zusammen mit billigen Sonnenschutzschildern eine Erhöhung der Lufttemperatur um +0,5 ° C (+1 ° F) oder mehr innerhalb weniger Minuten, nachdem die Sonne von hinter her Wolken oder die Wetterstation aus dem Schatten hervorkommt.

Meteorological observation networks are classified by their sensor and weather station spacing (how far apart are observations and measuring points from each other). With the advent of the Internet-of-Things (IoT), there is a strong focus on creating dense city-scale and local-scale weather station networks even at the expense of conforming to even the loosest measurement standards. 

Scientists seem to be forgetting that the promise of lower-cost wireless and sensor technologies does not, in fact, replace measurement know-how. This measurement know-how is a result of long-term experience and R&D, which takes time and, by default, drives up sensor costs of companies able to perform real measurements with scientific precision. Minimizing the "Observer Effect" of measurement systems takes know-how to avoid measuring unintended influences.  One such sin is mounting a rain bucket or a radiation shield close to an ultrasonic wind sensor. Cheap solar radiation shielding for air temperature sensors is another common mistake of amateurs and professionals alike. It is described in detail in "Will the BARANI DESIGN MeteoShield® replace the Stevenson screen as the new reference for climate change measurements?"

• Royal Belgian Meteorological Institute proves "The New Standard in Air Temperature Measurement is the BARANI helical MeteoShield®"

• Smart-City Mistakes to Avoid: The Question of Big-Data vs. Accurate-Data

• Big data vs. accurate data

When sensor networks don’t meet basic standards of measurement, smart-city sensor networks become bottomless money pits. They can turn great ideas into senseless infrastructure and clouds of deceitful or meaningless data.

Early in the 21st-century, cities started experimenting with Smart-City projects as part of the fourth industrial revolution (Industry 4.0) even before the phrase Internet-of-Things (IoT) became popularized. Now, at the current peak of the IoT craze fueled by artificial intelligence and data-processing hype, the first signs of a need to meet basic measurement standards of NIST, WMO/CIMO, NWS/NOAA, ASTM and ISO are becoming apparent.

The clearest example of the need to meet basic measurement standards can be found in urban climate monitoring since cities pose a number of challenges to accurate air temperature measurement. Pavement and building walls in the vicinity of weather stations reflect and radiate solar energy much more than grass turf and from every direction onto a temperature sensor causing large errors of air temperature measurement. Since the distribution of errors in air temperature measurement is not symmetric around the real-temperature value and is unique for each weather station installation, practical experience has shown that the quality of low-quality data does not improve with data set size.

Quality of air temperature measurement can be easily assessed by plotting together sunshine intensity (W/m²) and air temperature (°C/°F). Low-quality air temperature sensors, together with cheap solar radiation shields, show an increase in air temperature of +0.5 °C (+1 °F) or more within a few minutes of the sun coming out from behind clouds or the weather station coming out of a shadow.

One company that aims to change that is BARANI DESIGN Technologies. Their innovative MeteoHelix® design seems to break the mold of current weather station design.

COMPTUS Inc. of New Hampshire, a manufacturer and distributor of meteorological instruments, weather stations and sensors has on display BARANI DESIGN Technologies MeteoShield® Professional, MeteoWind® 2 and MeteoHelix® IoT micro-weather stations capable of meeting strict measurement guidelines of the NWS and WMO for long-term climatic observations of global warming. Known for their quality and affordability, these sensors and weather stations represent the state of the art that the world of meteorology has to offer for synoptic measurement.

Comptus Inc. has stand 341 at the 100th AMS Annual Meeting 14–16 January 2020 at Boston Convention and Exhibition Center, 415 Summer St., Boston, MA, USA.

Other sensors on hand from BARANI DESIGN Technologies will include the precise and robust and MeteoWind® Compact combined anemometer and wind vane with a preliminary MEASNET/IEC 61400-12-1:2017 edition 2 class A = 4.4 and class C = 4.7 along with the MeteoTemp™ temperature and humidity probe for professional AWOS weather stations.

Meteorologické stanice pre inteligentné pouličné osvetlenia, akou je  MeteoHelix® IoT Pro, sú schopné produkovať kvalitné údaje pre výskum klimatických zmien aj v mestských prostrediach, ktorým dominujú prehriate chodníky a steny budov od slnka.

Ideálna je montáž meteorologickej stanice na stĺpy pouličného osvetlenia, lebo stĺpy tvoria odstup od prehriatych stien budov, či chodníkov a stanice tak môžu merať správne. Hoci mestské meteorologické stanice so špirálovým štítom  MeteoShield® Professional dokážu presne merať teplotu vzduchu aj na priamom slnku s jeho sprievodnými odrazmi a sálavým teplom, stále sa musí dbať na výber miesta inštalácie tak, aby miesto reprezentovalo environmentálne faktory, ktoré chceme merať. 

Mestské meteorologické stanice je potrebné nainštalovať tak, aby do nich priamo neprenikal neprirodzene prehriaty vzduch. To by malo za následok meraniam dominujúci hyper-lokálny meteorologický fenomén. Je to možné, ak chce niekto merať extrémy účinkov tepelných ostrovov v mestách, ale ak je cieľom kvantifikovanie mestskej klímy na väčšej ploche, ideálnou voľbou sú stojany pouličného osvetlenia.

Priložené fotografie znázorňujú inštaláciu meteostanice MeteoHelix®IoT Pro a zrážkomeru SEB50 rain gauge od BARANI DESIGN Technologies na pouličné osvetlenie pri bytovom komplexe.

Wetterstationen, wie MeteoHelix® IoT Pro, für intelligente Straßenbeleuchtung, sind fähig die Qualitätsdaten zur Klimaveränderung für die Forschung auch in städtischen Umgebungen, in denen die von der Sonne überhitzten Gehsteigen und Gebäudewände dominieren, zu liefern.

Installation der Wetterstation an die Lampenpfählen ist ideal, da die Pfählen einen Abstand zwischen Wetterstationen und von der Sonne überhitzten Gebäudewänden bilden und somit können die Wetterstationen richtig messen. Obwohl die städtischen Wetterstationen mit spiralförmigem MeteoShield® Professional in der Lage sind, die Lufttemperatur auch bei direkter Sonneneinstrahlung mit seiner begleitenden Sonnenreflexionen und Strahlungswärmequellen genau zu messen, muss dennoch darauf geachtet werden, einen Aufstellungsort so zu wählen, dass er die Umgebungsfaktoren, die wir messen möchten, repräsentiert.

Es ist darauf zu achten, dass städtische Wetterstationen so installiert werden, dass künstlich erwärmte Luft nicht direkt in sie einströmt. Dies führt dazu, dass den Messungen der hyperlokale meteorologische Phänomen dominieren werde. Wenn man die Extreme städtischer Wärmeinseleffekte messen möchte, ist dies akzeptabel, aber wenn das Stadtklima jedoch auf einer größeren Fläche quantifiziert werden soll, sind Lampenpfahl- und Straßenbeleuchtunginstallationen die ideale Wahl.

Due to IoT, the cost of wireless sensor systems and meteorological weather stations has come down slightly for the following reasons:

1. Wireless modem costs have been reduced.

2. Power consumption of wireless data transmission has been reduced creating a chain reaction with the cost benefits of smaller electronics, smaller battery and smaller solar panel requirements.

3. What has not changed is the know-how required to produce high quality measurements. This know-how and its attention to detail from years of R&D differentiates the “random-number generators” from real measurement systems.

Despite the hype of big data, AI and advanced statistical methods, the early adopters of low-cost weather stations and meteorological sensors from most startup companies and agricultural sensor manufacturers have been, for the most part, dissapointed.

A second wave of IoT sensor adoption is upon us as researchers, smart-city managers and resilient-city initiatives are beginning to replace the first wave of low-cost meteorological sensors. High quality professional meteorological sensors are being introduced with the goal of maintaining long-term measurement stability in all weather conditions. After all, global warming is happening on a scale of about 0.01 °C (0,018 °F) per year, which is deeply withing the noise of short-term measurement. Thus long-term stability of measurement is critical to creating accurate climatic data sets.

New technologies on the forefront of professional IoT sensors include the MeteoHelix® IoT Pro micro-weather stations which are designed based on years of measurement experience of BARANI DESIGN Technologies.

Internet-of-Things innovation will be seeping into the forefront of AMS 2020 in Boston, MA this winter with the introduction of MeteoHelix® IoT micro-weather stations capable of meeting strict measurement guidelines of the NWS and WMO for long-term global warming observations.

While Europe has already adapted the first wave of low cost IoT meteorological sensors and weather stations with mixed results, the lessons learned can benefit the adoption of these technologies to let USA take the lead. Lessons learned from the first wave of IoT meteorological sensors have shown that data quantity does not replace data quality. Artificial intelligence (AI) and advanced statistical methods made good on identifying anomalies and sensor failures but fall short in compensating for systematic and long-term sensor measurement errors due to inadequate measurement system stability and the influences of the local environment. For now, the golden rule of science, “garbage in = garbage out” still maintains its merit.

Comptus Inc. of stand 341 will showcase the MeteoHelix® IoT professional weather stations and sensors conforming to NWS and WMO standards from BARANI DESIGN Technologies at the 100th AMS Annual Meeting 13–16 January 2020 in the Boston Convention and Exhibition Center, 415 Summer St., Boston, MA USA.

Other sensors on hand from BARANI DESIGN Technologies will include the precise and robust MeteoWind® 2 and MeteoWind® Compact combined heated anemometers with wind vanes with a preliminary MEASNET/IEC 61400-12-1:2017 edition 2 class A = 4.4 and class C = 4.7. Also showcased will be the MeteoTemp™ temperature and humidity probe and the new standard for precision atmospheric air temperature measurement, the MeteoShield® Professional, a helical radiation shield for professional AWOS weather stations.

2020 looks very promising for BARANI DESIGN Technologies s. r. o. after a notable 2019 with record revenue and sales of weather stations and meteorological sensors. Amid tough competition and supply side pressures, the spinoff technology division from BARANI DESIGN s. r. o. not only doubled its revenue for 2019 while quadrupling its international sales, but also made significant investment in manufacturing, intellectual property and R&D in preparation for the year 2020 and beyond.

Its sensor products are not only visually unique in the marketplace but offer the highest levels of precision for professional climatic measurements in all weather conditions. Its MeteoHelix® IoT weather stations achieved an outstanding U0 Sigfox wireless certification in 2019 and its LoRaWAN version offers identical wireless and measurement performance.

Included in the works for 2020 are a revolutionary compact wireless rain gauge able to accurately capture trace rain amounts down to 0.1 mm of rain while maintaining accuracy in torrential downpours as high as 40 mm/min. (2400 mm/hr).

Having achieved Sigfox Certification, the MeteoHelix® IoT personal weather stations are able to deliver wireless radio performance at the highest level in addition to their class leading measurement performance to WMO and NWS standards for all weather condition. For users this means that installation in agriculture and in smart cities can be hassle free, without having to take into account detailed coverage maps where Sigfox wireless coverage is available.

Radio performance of the latest generation of the MeteoHelix® personal weather stations has achieved the highest rating of U0 from Sigfox. MeteoHelix® is now commercially available and certified. More information can be found here: https://partners.sigfox.com/products/meteohelix-iot-pro-sigfox

The MeteoHelix® IoT LoRaWAN version is also available in for world wide distribution and features the same antenna design for top wireless performance.

With support from EURAMET, BARANI DESIGN Technologies was able to optimize the revolutionary helical MeteoShield® solar radiation shield to deliver a significant improvement in the precision of climate change monitoring. Its ability to reduce atmospheric air temperature uncertainty in all-weather conditions and climates by over 100 % over the most common multi-plate solar radiation shields and screens will result in a significant confidence improvement in confirming climatic changes not only in nature, but also in cities, deserts, rain forests and even arctic climates.

Climate change presents many challenges to society, including the effects of global warming and an increase in severe weather event frequency. Data from weather stations generated for short-term forecasting could be used to identify climate change trends, but higher quality measurements are needed. To achieve more accurate air temperature measurement, for example, sources of error caused by weather station siting and poor housing design need to be better understood.

Professional IoT weather stations and sensors conforming to World Meteorological Organization (WMO) standards from BARANI DESIGN Technologies are on display in the red show stand number 108 at the WEATHER • CLIMATE • WATER / EARTH OBSERVATIONS / GREEN ECONOMY 2019 expo in St. Petersburg, Russia today and tomorrow.

The meteorological instrument exhibition is taking place in parallel with the annual meeting of the Intergovernmental Council on Hydro-Meteorology of Commonwealth of Independent States (CIS) which is attended by hydro-meteorological services of the following CIS member countries: Azerbaijan, Armenia, Belarus, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, Uzbekistan, Ukraine.

The expo will showcase the following BARANI DESIGN Technologies sensors and micro-weather stations:

Smart street lamp weather stations like the MeteoHelix® IoT Pro are able to produce research quality climate change data even in urban environments dominated by pavement and sun-baked walls.

Installations on lamp posts are ideal as they put distance between weather stations and sun-heated walls of buildings so that weather stations can do their job properly. While urban weather stations equipped with a helical MeteoShield® Professional are able to accurately measure air temperature even in direct sunlight with accompanying sun reflections and radiating heat sources, care must still be taken to choose an installation location representative of the environmental factors which one wants to measure.

Care must be taken to install urban weather stations such that artificially heated air does not feed directly into them. This will result in the measurements being dominated by hyper-local meteorological phenomenon. If one wants to measure the extremes of urban heat island effects, this will be acceptable, but if the goal is to quantify the urban climate over a larger area, lamp post and street light installations are an ideal choice.

The accompanying photos show a street lighting installation of a BARANI DESIGN Technologies MeteoHelix® IoT Pro and SEB50 rain gauge within an urban building complex.

BARANI DESIGN Technologies will have on hand the latest meteorological technologies for climate research at the WEATHER • CLIMATE • WATER / EARTH OBSERVATIONS / GREEN ECONOMY 2019 expo in St. Petersburg, Russia on October 9-10, 2019.

The exhibition will take place at the new Expoforum Convention Center in St. Petersburg, Russia, and will be supported by Roshydromet – Federal Service of Russia on Hydrometeorology and Environmental Monitoring.

The expo will showcase the following BARANI DESIGN products:

This exhibition is one of the world’s most significant in the field of hydrometeorology, environmental monitoring, earth observations and green economy for the republics of the former Soviet Union including:

• Armenia

• Azerbaijan

• Belarus

• Estonia

• Georgia

• Kazakhstan

• Kyrgyzstan

• Latvia

• Lithuania

• Moldova

• Russia

• Tajikistan

• Turkmenistan

• Ukraine

• Uzbekistan

Green-roofs are here to stay. Their benefits in the reduction of the heat-island effect are known, yet not well quantified. The limitations of current sensor and weather station technologies limit the quality of urban climate research due to error producing influences of sun-heated building walls and pavement. Large measurement errors in meteorological instrumentation due to inadequate 360-degree solar heat shielding with adequate ventilation severely limit urban meteorological data quality. Yet one sensor company is about to change that.

The application of helical MeteoShield® Professional technology as part of the MeteoHelix®IoT Pro micro-weather stations is enabling researchers to achieve WMO precision in air temperature measurement in inner-cities. The multiple degree errors of conventional multi-plate radiation shields and their fan-aspirated solar shield counterparts are a thing of the past with the application of BARANI DESIGN’s helical shielding technology which has been verified by the World Meteorological Organization (WMO).

As part of its educational support program, BARANI DESIGN Technologies provides deep discounts on meteorological sensor technologies to educational institutions and researchers like Assoc. Prof. Dr. Eva Pauditšová , PhD. from Comenius University in Bratislava, who is performing research on the real climatological benefits of green roofs in inner-cities in cooperation with Chief Architect Ing. arch. Ingrid Konrad (Bratislava City Hall) and the support of the city of Bratislava magistrate.

“Thanks to the technology found in the MeteoHelix IoT Pro micro-weather stations we are finally able to accurately determine the cooling effect of green areas in the city,” says Assoc. Prof. Dr. Eva Pauditšová , PhD. who’s research builds on the successful international project Horizon 2020 RESIN - Climate Resilient Cities and Infrastructures. Her current focus is on the sensitivity of urban structures and microclimates to the effects of large scale climatic changes due to global warming and is part of the international project Horizon 2020 ARCH – Advancing Resilience of Historic Areas against Climate-related and other Hazards.

With the launch of its latest iteration of the elliptic cup anemometer, the MeteoWind® Compact, BARANI DESIGN Technologies is poised to make another dent in the wind energy sensor market as dominated by Thies Clima, NRG, and Vector Instruments.

MeteoWind® Compact shares the proven robust cup design of its big brother MeteoWind® 2, thereby simplifying field service. It is the elliptic cup design which ensures MEASNET linearity [2] (Sample MEASNET calibration report) and enables MeteoWind® anemometers to excel not only in precision wind measurement for wind resource assessment but to also offer superb snow shedding for winter operation. A heated version of MeteoWind® Compact is also available.

• As a direct replacement for NRG anemometers, the MeteoWind® Compact offers higher precision, requires less hardware to install since it offers wind speed and wind direction measurement in one compact device and is available at a better price point.

• As an alternative to ultrasonic anemometers, MeteoWind® Compact offers higher precision and data reliability in bad weather and in winter. It is also bird damage resistant which is a major cause of ultrasonic anemometer failure. Every year, up to 30 % of ultrasonic anemometers are damaged by birds biting out their sound producing ultrasonic transducers. [1]

• Compared to Thies 1st Class and Vector Instruments anemometers, it offers comparable if not better Class 1 precision and accuracy despite not yet having the MEASNET/IEC 61400-12-1:2017 EDITION 2.0 certification. Additionally, it also offers combined wind speed and wind direction measurement in one device, thereby simplifying installation.

For meteorological applications, MeteoWind® Compact offers significantly greater accuracy as required by the WMO and NWS [3], thereby making the anemometers maintenance free for many years after installation.

MeteoShield® Professional begun sea borne testing on marine buoys in the Asia Pacific region last week. Compared to existing multi-plate solar radiation shield technologies and even fan-aspirated shields, it offers a significant improvement in all weather precision for air temperature and air humidity measurement. Compared to fan-aspirated shields, it has the added benefit of superior reliability.

This advantage in measurement precision is hoped to make a significant contribution to the quality of climatological measurements and is poised to increase confidence and precision in quantifying global warming and its associated climatic changes to the region.

It’s a sad day when past innovators resort to false claims instead of innovation. Five months after Rainwise contacted BARANI DESIGN Technologies about the MeteoHelix® IoT Pro personal weather station, did Rainwise make a claim to be the 1st IoT weather station on the market.

The MeteoHelix® IoT Pro personal weather station begun sampling to customers in the spring of 2018 as a year long testing campaign begun. Almost a year later, Rainwise begun announcing “the world’s first compact, solar powered, commercial grade, true IoT MK4 Weather Station.” with pre-orders of 6,000 plus units. A few months later announcements that the not yet released MK4 “IoT weather station has already secured purchase commitments of over 7,000 units in 2019 without the product being officially released” are being claimed on the https://www.iottechexpo.com website in the Rainwise company description.

USA is known for innovations

USA is known for innovation and the MeteoHelix® is proof of that. While we believe that no one can claim to have the first IoT weather station, the MeteoHelix® IoT Pro brings a number of firsts to the market. Its ability to measure at World Meteorological Organization (WMO) and National Weather Service (NWS) precision standards for under $600 is unprecedented in the professional meteorological world and the personal weather station marketplace.

Proof of its pedigree can be found in WMO research papers like the RMI comparisons where its innovative helical shape proved to surpass the precision of professional meteorological networks monitoring climate change. Neither Davis nor Rainwise weather stations can claim to provide the professional meteorological data quality of the MeteoHelix even with their fan-aspirated counterparts.

While the MeteoHelix® is currently manufactured in Slovakia, its roots and inventor are “Made in USA.” RPI educated and groomed at Boeing, the MeteoHelix®’s roots share this pedigree. Plans are in the works to bring the MeteoHelix® personal weather station production back to the US. A self-cleaning rain gauge is also in the works. Please stay tuned and enjoy the view.

Ever since 1974 RainWise Inc. has been at the forefront of innovation in the personal weather station business. Others like Davis, AcuRite, La Crosse, Oregon Scientific and Netatmo followed suit with Davis carving out the largest share of the premium middle market where data collected by the weather station was somewhat usable, even by meteorological services. Despite the fact that each personal weather station came with its own set of innovations and looks, they all lacked the accuracy and long-term data stability to make it in the professional meteorological world.

Personal weather station reinvented

In 2018, we shrunk a professional solar powered weather station (AWOS) costing over $3,000 into a compact personal micro-weather station using new IoT wireless technologies and sensors. Its patented helical design taken directly from the field proven MeteoShield® Professional allows this personal weather station to meet WMO measurement quality standards in all weather conditions unlike any of its aforementioned competitors. The MeteoHelix® personal weather station is available worldwide.

The MeteoHelix® weather station is the first IoT device to demonstrate a LoRaWAN Internet of Things wireless network on the island nation of Samoa in the South Pacific during the Pacific Meteorological Council (PMC-5) meeting. Its secure encrypted meteorological data connection uses The Things Network LoRa server to rout data to the allMETEO.com meteorological cloud platform as part of an early warning weather monitoring system demonstration. The ease of deployment of the MeteoHelix® weather stations makes them unique in the marketplace.

Designed to survive cyclone, hurricane and typhoon force winds and direct impacts of flying debris, the MeteoHelix® weather station is the only weather station on the market today that can reliably function through the destruction they bring.

We would like to thank the the Government of Samoa, the Ministry of Natural Resources and Environment (MNRE) as the hosts of the PMC-5 meeting and Varysian, the organizers of the hydrometeorological equipment exhibition, for making this demonstration possible.

With the fifth meeting of the Pacific Meteorological Council (PMC-5) in Apia, Samoa quickly approaching, BARANI DESIGN Technologies team has set off to showcase the latest meteorological technology to the PMC's NHMS members and senior government officials from SPREP member countries. Additionally, their development partners, Council of the Regional Organisations in the Pacific (CROP), United Nations' agencies, collaborating organisations and institutions with also be present to discuss mitigation strategies of accelerated global warming and the adoption of early warning weather monitoring systems.

BARANI DESIGN Technologies will showcase the MeteoHelix® weather stations which are capable of surviving impacts of flying debris as found in cyclones. Being the only professional weather station to be able to survive such conditions while meeting WMO requirements for precision and accuracy of measurement, makes the MeteoHelix® IoT Pro a one of a kind proposition for island nations most affected by climate change.

The hydrometeorological equipment exhibition will be held on 5 - 9th August 2019 alongside the PMC-5 and is organized by Varysian.

Its worth noting that the temperature time constant listed for the HMP155 is at a hefty 3 m/s airflow speed as shown in the photo from its manual. Thus the HMP155 temperature time constant converted to still air will, unfortunately, be significantly higher and hence the HMP155 temperature measurement error due to fluctuating air temperature will NOT be per WMO recommended guidelines as specified in the WMO – The CIMO Guide – Guide to Meteorological Instruments and Methods of Observation, 2014 Edition updated in 2017.

Due to the slow time response of this temperature sensor, an air temperature fluctuation of 2 °C over a period of 2 minutes in 3 m/s airflow will show a measurement error of 0.29 °C (at 3 m/s air speed) on top of the basic sensor accuracy/uncertainty.

Flow obstruction caused by a radiation shield will significantly increase this error for low wind speeds. Despite the status quo, it will be very hard to justify the HMP155’s use for precision climatic measurement. In 1 m/s air, the time constant can rise to 35 seconds and in 0.5 m/s air to 49 seconds, thus producing errors over 0.5 °C due to only the sensor’s slow response time.

• To reduce most air temperature errors due to sensor response time below 0.2 °C a sensor time constant of 13 seconds is required for air speeds of <1 m/s.

• To reduce the errors below 0.1 °C a τ63.2 % time constant of 7 seconds is required for air speeds of <1 m/s.

• The above values were calculated using the online Web calculator at the following link:

  • Influence of sensor response time (τ 63.2%) on climatic temperature measurements

• Below results were calculated using the Web calculator for sensor step response at this link:

  • Calculation of sensor stabilization time for climatic temperature measurements with heated humidity sensors

As part of a pilot project on water management started in July 2018 in New Caledonia in the South Pacific, the MeteoHelix® IoT Pro weather stations connected through the wireless Sigfox network will provide critical weather information at never before possible all-weather accuracy. The quality of weather information supplied by the new MeteoHelix® weather stations is such, that it will be able to be used for climatological monitoring of global warming in addition to its primary use for water management and agriculture. The weather stations were supplied by http://www.iot.nc, a leader in IoT development in the South Pacific.

Global Temperature Change = Green House Gas Emissions - ( Natural Plant Life - Agricultural Land Use )

• As Quantity of Green House Gases increases, global temperatures rise. ⇧

• As Natural Plant Life increases, CO2 is absorbed and global warming decreases. ⇩

• As Agricultural Land Use increases at the expense of Natural Plant Life, less CO2 is absorbed and global temperatures increase. ⇧

Increases in CO2 in the atmosphere help promote plant life growth to quickly absorb excess CO2 and return our planet’s climate into balance. As agricultural land use expands, natural pant life areas are converted into agricultural land through the destruction of natural vegetation.

Agricultural land takes up about 37 % of earth’s surface. Since growing seasons last only a few months and crops are harvested just at the peak of their CO2 absorption capabilities, agricultural land absorbs CO2 only a small part of each year. This simple fact creates a large decrease in CO2 absorption capability compared to land with natural vegetation which absorbs CO2 year round.

While the contribution of agricultural equipment to CO2 and equivalent emissions is currently less than 10 % of the total worldwide CO2 emissions (see chart), its contribution to the reduction of natural vegetation has not been accounted for.

Since 1960, both green house emissions and reduction in natural plant life due to expansion of agricultural land are both upsetting the energy balance of our ecosystems in the direction of global warming as shown below:

• CO2 concentrations have increased from 317 to 409 ppm by 30 % ⇧

• Agricultural land use has increased from 1.38 billion to 1.58 billion by 15 % ⇧, leading to a decrease world wide in natural vegetation.

Can recision agriculture solve global warming?

Precision agriculture has been around for years, though no one knew how to name it. Since the invention of the personal weather station with a tipping-bucket rain gauge by RainWise Inc., farmers have had access to somewhat accurate local meteorological data, yet not many knew how to take full advantage of it. With the advances in computing power, agricultural equipment and data processing techniques, higher precision data becomes more valuable to take full advantage of the possible increases in farming efficiency. This, in combination with the looming Internet-of-Things technological revolution, has lead to the reinvention of the personal weather station as a professional quality instrument by BARANI DESIGN Technologies. Its MeteoHelix® micro-weather stations are able to produce meteorological data of higher quality than most current climatological networks (3), in excess of World Meteorological Organization (WMO) requirements, for a fraction of the price of the most popular RainWise and Davis personal weather stations.

Since farming is highly dependent on weather, farming decision making is dependent on good meteorological data quality. New farming efficiency gains through high-quality meteorological and soil data can significantly increase crop yields. If sensor and data affordability is maintained not at the expense of data quality with the goal of reversing global warning, as with the MeteoHelix® weather stations, increases in crop yields will allow for a reduction in global agricultural land use. Reduction in global agricultural land use leading to expansion of natural vegetation areas will offset higher CO2 emissions even while our world population and emissions expand. The climate change equation will be moved closer to balance again.

Foreign investment in weather networks such as TAMHO & Smart Agric is proof of the value of meteorological data, not only in Africa, but all over the world. Weather related economic risks create financial opportunities on a scale of tens of billions of dollars globally. Weather insurance companies and weather risk management is thriving as weather derivatives have become a traded commodity in the field of weather risk management.

Managing weather risk

As natural vegetation yields to farm land expansion, reduction in rain water catchment makes not only our economies more susceptible to weather risk, but contributes to global warming, thus fueling the growth of weather derivatives which benefit from global warming and its related weather volatility. The good news is that both vegetation and water catchment can be managed and recaptured by supporting natural processes. Accurate monitoring of critical micro-climates on which natural processes rely to balance and slow global warming, first requires high-quality and high-density meteorological networks with superb long-term stability of measurement, whose data can be traded to create funding for climate stabilization projects.

Plan of action for climate change

Quality weather data complemented by detailed action plans will permit timely reaction to destabilizing effects of erosion of natural processes and to reverse micro-climate changes from human-machine interaction with the environment. Many countries, in an effort to manage water and mitigate future drinking water risk, have begun forming such action plans, many of which include two tiered networks of large and small meteorological and hydrological weather stations like the MeteoHelix®.

Meteorological capacity building for profit

Africa, Central & South America, South Asia and Oceana countries require their own meteorological networks. Secondary/tertiary weather networks such as TAHMO and Smart Agric, and their benefits, remain mostly in the hands of foreigners. Such networks need not be an a red expenditure in their meteorological departments’ budgets but an opportunity for meteorological departments to become self-sustainable enterprises. Income from risk mitigation and weather insurance can also mean saving of lives, crops, livestock and local economies.

In meteorological weather prediction, every student of computational fluid dynamics (CFD) knows that one cannot obtain any relevant levels of accuracy without accurate boundary conditions and initial conditions (input data), which equates to accurate, surface, near surface and upper air meteorological data.

Above every square meter of ground there is over 7,000 kg of air in the troposphere alone. Troposphere is where weather happens. It also contains 99 % of all atmospheric water vapor. It also contains most of the mass and energy of the whole atmosphere. [1]

The acceptable magnitude of error

The amount of energy trapped in the Troposphere is striking. On a 37 °C summer day with 95 %RH humidity just one kilogram of air contains about 137 kJ of energy. A +3 °C error in air temperature reading due to inadequate solar shielding [2] will erroneously increase this figure a whopping 16 % to about 159 kJ/kg. A large 5 %RH humidity deviation will only cause one fourth the error. Applying even a fraction of this error to boundary conditions of a CFD weather model of the local troposphere will lead to uncorrectable errors in numerical simulation and erroneous results and forecasts.

Validation counts

Having worked on wing design for a company which arguably makes the most efficient airplanes in the world, I had a first-hand look at complexity of numerical fluid simulations and their susceptibility to error. Results from numerical weather prediction models require validation. Just like airplane companies and even Formula 1 use wind tunnels to validate their CFD simulations, meteorologists validate with surface, near surface and upper air meteorological data. Yet there is one big difference. The meteorological weather prediction models have much more complex inputs and boundary conditions, thus more chance for error. Unfortunately, false validation seems to be a trend as many meteorologists are love to claim high weather forecast accuracies. I think we all intuitively realize the reality in weather critical situations is quite different.

About the author

Jan Barani is the inventor of the helical MeteoShield® Professional and the CTO of BARANI DESIGN Technologies which brought to the professional meteorological world the 1st micro-weather station, called the MeteoHelix® IoT Pro, to be able to meet WMO guidelines for precision meteorological measurement in all weather conditions and all climates.

WMO Statement on the state of the global climate change has been published. It summarizes the symptoms of climate change. The detailed report can be found at this link: https://library.wmo.int/doc_num.php?explnum_id=5789

Action required - the outlook is very grim

While climate trends outlined in the 25th aniversary WMO Statement on the State of the Global Climate in 2018 paint a grim picture about the speed of earth’s climate change, the world meteorological and political leaders need to refocus to manage not only the easiest to measure symptom of climatic change, CO2 concentrations, but also the root causes as exemplified by the scientific community.

Fight the cause, not the symptoms

Arguably, the leading contributor to accelerated global warming is the erosion of natural vegetation and rain forests by unsustainable farming techniques and poor urban planning both of which can be grouped into what is known as the erosion of water catchment areas. Erosion of water catchment areas leads to the reduction in CO2 absorbing plant life and the acidification of oceans. Plankton has a great capacity to absorb all the CO2 that humans can muster, the problem is that the ocean must first absorb this CO2 which leads to its acidification and destruction of many sensitive organisms like corals which are homes to many oceanic organisms.

As silent wars are fought by embargoes and computer viruses to disrupt economies and destabilize governments, collateral economic damage due to weather events has become a weapon of war. Governments are staring to implement bans on weather data export and requiring more and more that foreign weather services maintain weather data infrastructure within their borders.

In the future, detailed weather data will become sensitive information for many countries. This will pose a significant challenge to the World Meteorological Organization (WMO) in maintaining accurate climatology information, as raw meteorological data and their metadata may become a controlled commodity.

SENSOR DONATION TO ENVIRONMENTAL RESEARCH

To thank world-wide environmental researchers for their efforts in the fight against accelerated global warming, BARANI DESIGN Technologies is planning to donate 100 helical MeteoShield® Professional solar radiation shields, valued at 20,000 Eur, to research organizations. Interested parties should contact BARANI DESIGN Technologies directly to secure their part of this sensor donation package. Research organizations can also sign up at the World Meteorological Exhibition on June 5, 6, 7 at stand 6020, which will be held in Hall 4 of Palexpo in Geneva, Switzerland.

Water vapor is not officially considered to be a cause of man-made global warming because it is abundant and CO₂ is much more convenient to measure, regulate and tax. The fact that water vapor does not persist in the atmosphere for more than a few days, makes its concentrations highly variable and harder to quantify on a global scale without good quality weather networks everywhere. Its concentrations can reach 100 times that of CO₂ and its ability to trap heat is double. Additionally, fog and clouds reflect and absorb immense amounts of incoming solar radiation and moderate climatic temperatures. The water cycle reduces temperature extremes and redistributes heat throughout earth’s climates.

Three MeteoHelix® micro-weather stations were installed to monitor new technology experiment to help prevent frost on budding wine grape plans at the renowned Hö­he­re Bun­des­lehr­an­stalt viticulture school in Klosterneuburg near Vienna, Austria. These precision weather stations are powered by the sun and connected to the Sensor Network Services GmbH LoRaWAN wireless network to provide critical real-time information to help evaluate the success of this new technology. Differentiated by their helical shape, they are able to provide world class measurements for a fraction of the cost of comparable accuracy meteorological technologies.

The variability of weather over the recent decade has caused grape wine damage in the millions of euros each year due to frost. This experiment is very significant due to the fact that it sits within a vast wine region stretching for hundreds of kilometers from the Tokaj of southern Slovakia and northern Hungary to the southern Moravia region of the Czech republic and all the way to the Vienna region known for its wine schools and superb white wine production.

Ultrasound and wildlife reserves

Ultrasonic anemometers seemed like the solution for maintenance-free wind measurement, yet nature had its say. Their ultrasound, while being inaudible to humans, is disturbing enough to natural wild life so that each year, birds destroy about 1/3 of all ultrasonic sensors by biting out their ultrasonic transducers as reported by the German Met Office. [1] This leads to the question of whether ultrasonic sensors are environmentally friendly and whether they should be allowed in wildlife reserves and national parks or if their application should be limited to industrial use?

Cup anemometer renaissance

New advances in electronics and manufacturing are enabling mechanical cup anemometers to not only outlast their ultrasonic counterparts but to maintain their accuracy advantage and to remain the mainstay of meteorological measurement and of the precision wind energy industry.

BARANI DESIGN Technologies of Slovakia will create a strategic partnership with Comptus Inc. of USA, who is one of the only two producers of the most widely used anemometer for wind energy applications worldwide. The immediate benefits of this partnership will include:

• MeteoShield® Professional will be soon available in a Made-in-USA version

• MeteoHelix® IoT Pro micro weather stations will soon be available in Assembled-in-USA LoRaWAN and Sigfox version with NB-IoT to follow

• Comptus Inc. will become a USA & worldwide distributor and integrator of BARANI DESIGN anemometers, weather stations and sensors

• BARANI DESIGN will become a worldwide distributor of the A75-101 & A75-104 anemometer and A75-302 wind direction vane, the direct equivalents of the well known NRG #40 anemometer and NRG #200 wind vane. These products were also sold through Second Wind and Vaisala as the C3 anemometer and PV1 wind vane

In a technology sharing program, both companies will join forces to develop a low-cost wireless precision wind measurement solution to complement the MeteoHelix® IoT Pro wireless weather stations and to directly compete in the high-end and middle market segments in agricultural weather station applications. The MeteoHelix® and MeteoWind® Compact combination will become the only affordably priced weather station solution to meet the Wold Meteorological Organization (WMO) measurement standards. This meteorological sensor solution is aimed at putting precision back into precision agriculture which is currently being dominated by measurement equipment not conforming to worldwide measurement standards.

Vandalism-tolerant meteorological network

• A high-density meteorological network based on affordable WMO conforming micro weather stations is inherently vandalism-proof.

• Larger data density allows the network to absorb a large number of end-point weather station vandalism failures while maintaining sufficient data density.

• Redundancy of wireless data coverage based on IoT technologies affords the network even more reliability.

• Combined with a micro weather station designed to prevent data access to thieves and with minimal resale or recyclable material value, this will de-incentivize serial vandals and thieves.

What weather station was designed from the onset for vandalism tolerant meteorological networks?

• MeteoHelix® IoT Pro micro weather stations are designed to for vandalism tolerant meteorological applications requiring the utmost precision of measurement per World Meteorological Organization (WMO) standards.

• Independent wind sensor apart from the temperature, humidity, atmospheric pressure and sun sensors create a modular system able to conform to all use cases and needs.

Can the MeteoHelix® bring on a new revolution in professional meteorology? When many meteorological departments are cutting costs, it has become harder and harder to justify expansion of meteorological networks, especially for countries stuck in recession such as in Africa and South America. What if what was once before thought impossible now became possible?

A professional weather station meeting the stringiest World Meteorological Organization (WMO) accuracy requirements for sub 500 Euro? New technologies like the award winning helical MeteoShield® Professional and the advent of low-power wireless technologies enabled BARANI DESIGN Technologies to shrink a professional weather station and to make it so simple to install and use that even your grandma can use it.

“Precise enough for the professional, easy to use for everyone.”

This compact professional weather station enables just about anyone to have professional grade meteorological data in their backyard. While its affordability makes high-density meteorological networks not only possible but also financially viable.

The MeteoHelix® IoT Pro – Sigfox version will be presented and displayed along with its allMeteo® cloud platform at Sigfox Connect 2018 in Berlin Germany.

While temperature sensors are getting more and more accurate, uncertainty of air temperature measurement has remained mostly unchanged over the past decades. Where once iconic Stevenson screen shelters dominated the professional meteorological landscape, they are now becoming rarer and slowly replaced by smaller cheaper multi-plate radiation shields and fan-ventilated shelters. Are they still the benchmark of precision air temperature measurement or are upcoming technologies like the helical radiation shield from BARANI DESIGN Technologies ready to send them the way of the dinosaurs?

Measuring true air temperature is complicated. AWOS weather stations measure "near surface atmospheric air temperature" at a height of two meters according to World Meteorological Organization (WMO) standards. They usually use sensors calibrated in a liquid bath in adiabatic conditions, while real measurement inside radiation shields and Stevenson screens takes place in anything but adiabatic conditions. In layman's terms, sensor temperature in the real world is never in balance with air temperature, thus measurement error (uncertainty) due to varying sensor construction, sensor reaction time (time constant) and self-heating along with radiative heating and cooling is unaccounted for.

True air temperature

What is "true near surface atmospheric air temperature" is somewhat of a mystery. Before comparing various air temperature sensor systems, one must first understand what one is trying to measure... to understand what true air temperature is.

Like any substance, air is prone to heating and cooling through well know energy flows like solar radiation, infrared radiation, convection, conduction and emissivity. Other sensor related influences include dew condensation, evaporative cooling or phase transitions, direct, diffuse and reflected solar radiation, self-heating and of course, the above mentioned calibration procedures.

What affects real air temperature

First, lets take a look at heating from radiative sources such as the sun and infrared heat radiating from the surroundings, which seem to dominate air temperature error and uncertainty. Even though air is mostly transparent, it is well documented that each of its composing gases has a certain light sensitivity or absorbance spectrum and also emissivity (radiative cooling). This radiative heating of air accounts for the difference between incoming solar radiation from earth's sun and radiation reaching ground level as shown in yellow in the accompanying plot. A familiar example is the absorbance of UV light in the upper atmosphere by ozone molecules. 

Just like every other substance, air also has the ability to cool itself by radiating heat away in the form of infra-red radiation. This property known as emissivity is different for every material and color and contributes to the error which effects our measurement quality inside every solar screen and solar radiation shield used to house meteorological air temperature sensors.

The energy balance of our measurement systems effects the temperature our sensors read. In the professional community, it is widely believed that a larger solar screen is more accurate. Why some may think this, we will attempt to explain later, but first lets flip the cards around and look at air temperature from the perspective of an air molecule flowing in the wind two meters above ground according to WMO standards. (For this illustration, it is not important whether it is N₂, O₂, Ar, CO₂, H₂O, O3, NO, NO₂ or any other molecule or dust particle composing air.)

Temperature from the viewpoint of air

On a partly sunny spring day with remnants of intermittent snow cover over grassy fields an air molecule called Caeli moved through the shade of a cloud, where it reached an equilibrium temperature of 15 °C. In the shade, the atmosphere was in balance and Caeli was emitting exactly the same amount of heat through emissivity as was receiving from the surroundings like the ground, vegetation and from diffuse solar radiation while the sun's direct solar radiation remained hidden behind a cloud. 

Crossing the threshold of shade into the sun, direct solar radiation bombards Caeli with five times the energy of diffuse radiation. The ground below is of no help since it too is heated by the sun and radiating more heat toward Caeli's bottom than the ground in the shade of a cloud. While exact calculation of Caeli's warmup is beyond this article, her temperature rise is almost immediate and Caeli and her molecular friends find themselves dancing at 3 °C higher temperature than in the shade. 

Stevenson vs. BARANI

As Caeli's journey continues, she suddenly hits a white gauntlet. Smacking directly into a Stevenson screen shelter, Caeli flips upside down and slides through its slots into a chamber hidden from the sun and filled with thermometers. She quickly shakes off the extra heat accumulated in the sun and peacefully slides past a temperature probe. It remains a mystery what her exact temperature was and if she had enough time to find her new temperature balance before squeezing through the back-side louvers and out into the free air in the sun where she quickly regained her warmth. Was Caeli’s temperature drop measurement error caused by the Stevenson screen?

A few meters later her head starts spinning again as she finds herself skimming past a temperate probe. This time she entered a helical solar shield and before she even noticed being in the shade, she rubbed elbows with the temperature probe. The shield's smaller size and easy air access to the sensor gave Caeli almost no time to shake off accumulated heat from the direct sun as compared with the Stevenson screen. 

The future of air temperature measurement

• What did the sensors inside the Stevenson screen and BARANI’s helical MeteoShield® Professional measure?

• How was the measured air temperature affected by each shelter?

• Which measured temperature is closer to the real atmospheric air temperature?

These are the questions aimed to be answered by the Consultative Committee on Thermometry of BIPM in their 2023 - 2027 roadmap and by a new project being launched this year by EURAMET. The first goal, however, will be to identify all of the components of uncertainty by the International Surface Temperature Initiative or ISTI which will start preparing a joint paper with members of CCT on this topic.  

WMO radiation shield comparisons

A more detailed comparison of BARANI DESIGN MeteoShield® Professional and the Stevenson screen shelter can be found in a WMO radiation shield comparison study by the Royal Meteorological Institute of Belgium (RMI). “Intercomparison of Shelters in the RMI AWS Network”

A notable study was also performed by METEOMET where multiple radiation shields were compared in a winter alpine setting for the effects of snow and sun reflections. “An experimental method for the evaluation of snow albedo effect on near surface air temperature measurements.”

DESIGN UPDATE 2020

The class leading MeteoShield® Professional has been significantly improved in 2019 based on data from WMO testing and new manufacturing possibilities. Uncertainty of measurement has been lowered significantly for all weather conditions and robustness has been improved as demonstrated by customer experience.

Following a long-term study by the Royal Belgian Meteorological Institute the results of the performance of the patented design of the MeteoShield® Pro, on which the MeteoHelix® IoT Pro micro weather stations are based, were finally published at on October 08, 2018 at the CIMO-TECO-METEOREX - WMO as part of the Meteorological Technology World Expo 2018.

Under the skeptic eye of the Royal Belgian Meteorological Institute, two units of the MeteoShield® Professional were paired against two fan-ventilated atmospheric air temperature measurement systems used as the ultimate atmospheric air temperature references.

The results should have been predictable

Until the introduction of the helical (spiral or twister type) radiation shield by BARANI DESIGN Technologies, the results of radiation shield testing were mostly predictable. Fan-ventilated (fan-aspirated) shields that use an electric fan to drive air around a temperature sensor typically surpassed the accuracy of naturally ventilated multi-plate shields or Stevenson screens by 0.5 °C or even by up to 3 °C. Some of the most reputable air temperature sensor companies and their customers placed $300-$1500 precision sensors into expensive poorly performing shields only to end up with mediocre accuracy for a large financial investment. Affordable Davis Vantage Pro weather stations were many times able to surpass the accuracy and reliability of professional weather stations at 1/10th the cost. This was the status quo.

BARANI vs. STEVENSON

While many Met offices still cling to the old style Stevenson screen shelters for their reference measurements, a new era of precision atmospheric measurement may be upon us. While Stevenson created his shelter to perfection with the technologies at hand, new technologies of the 21st century allowed Jan Barani, educated at Rensselaer Polytechnic Institute (RPI) in aeronautical engineering, to create something not only more precise but arguably beautiful. Fan ventilation upgrades to the Stevenson screen design kept pace with modern fan-ventilated solar shields and screens until the introduction of the helical radiation shield design by BARANI DESIGN Technologies.

MeteoShield® Pro - the new standard of atmospheric temperature measurement

Quoting the results of the Royal Belgian Meteorological Institute study, the standard deviation error of the patented helical shield design of MeteoShield® Professional is 1/2 of their fan-ventilated shield which in layman’s terms means the helical MeteoShield® Pro is twice as accurate. Whats more, the standard deviation of the MeteoShield® Pro is 18 % lower than their fan-aspirated Stevenson screen. Once again in layman’s terms we can say that the helical MeteoShield® Pro is 18 % more accurate than a fan aspirated Stevenson screen. If that was not enough, the helical MeteoShield®’s precision in rainy conditions is almost twice as good as that of the fan-aspirated Stevenson screen reference and almost four times better than the RMI fan-ventilated shield.

Stable platform for climatological measurement

Climatology has a special set of requirements for monitoring global warming. Temperature minimums and maximums are not the most relevant values, actually they are only good for publicity. Average yearly temperatures are also only part of the picture. A detailed statistical analysis encompassing such terms as Standard Deviation, Skewness, Kurtosis, 1st Quartile, Median and 3rd Quartile in addition to the Minimums and Maximums need to be considered together. Effects of rain and snow, snow on the ground and the effects of ground color and ground type around the radiation shield or Stevenson screen are also important to consider. Taking all these variables and statistical terms into consideration, “MeteoShield® Professional is really the only measurement platform that comes even close to fulfilling all the requirements. It is not perfect, but comes closest to finally being able quantify with confidence, the very slow (0.7 °C per 100 years) climatic changes, which up till now, were stuck in measurement noise.

Is BARANI better than Stevenson?

• “The BARANI's shelters have shown excellent results with a very limited heating under strong radiation. The mean overheating is as low as 0.2 °C for medium global solar radiation and low wind speed (<1 m/s). It is unclear why the overheating is lower for higher global solar radiation.”

• “Despite the fact that the BARANI shelters are not articially ventilated, their performances are better than our articially ventilated compact shelter.”

Quoted from the Intercomparison of Shelters in the RMI AWS Network, Luis Gonzaalez Sotelino, Nicolas De Coster, Peter Beirinckx, Pieter Peeters, Royal Meteorological Institute of Belgium, 3 avenue Circulaire 1180 Uccle, Belgium.

The 2018 show will launch MeteoWind® Compact anemometer, ezMETAR weather stations and MeteoHelix® research-grade micro-weather stations based on the award-winning helical MeteoShield® Pro design.

The inventor of the helical radiation shield will be presenting and explaining the principles behind this innovative helical weather station. After over 12 years of research and 10 years of field experience, MeteoHelix® weather stations based on the patented design of the helical solar shield, allow previously difficult-to-achieve measurement accuracy, precision and reliability in an economical all-in-one weather station. These solar powered and wireless all-in-one weather stations are able to remain operational for 6+ months without sunlight and can use satellite data uplinks for meteorological data with satellite LoRaWAN gateways.

BARANI DESIGN Technologies will be exhibiting the helical MeteoShield® Professional, MeteoHelix® and professional AWOS weather stations in booth 10005 at the Meteorological Technology World Expo on 09-11 October 2018 in Hall 8, Amsterdam RAI, in the Netherlands.

MeteoHelix® IoT Pro micro weather stations designed to achieve strict accuracies as set by the World Meteorological Organization (WMO) have been deployed to crop field experiments throughout Europe by Monsanto as part of Skymaps s .r .o. precision agricultural solution. The precise measurement properties resulting from their helical, spiral or twister design makes these wireless weather stations unique in the marketplace.

Recent advancements in wireless technologies enabled BARANI DESIGN Technologies to design a complete wireless weather station into a cavity where only a sensor could fit before. This new helical weather station design is not only accurate and compact, but also economical. With the target MSRP end-user price set at 499 Euro (VAT exclusive) or $550 USD, the measurement quality and installation convenience offered can be considered a steal. For precision agriculture experiments where accurate climate monitoring is of utmost importance, the long-term measurement stability offered by the self-cleaning MeteoHelix® IoT weather stations is a strong selling point, along with their ease of use, installation and operation.

The MeteoHelix® IoT Pro is not the only meteorological measurement technology being evaluated by Monsanto. Understory weather stations have been in evaluation for some time. MeteoHelix® IoT Pro is however the most accurate, theft proof, vandalism proof weather station on the market today.

Will the most established player in the wind resource assessment industry soon copy the MeteoWind® 2 anemometer with wind vane configuration from BARANI DESIGN to give up its lead in anemometer design? Would this finally lead to the adoption of combined wind sensors into the IEC 61400-12-1?

The "First Class" anemometer series are arguably the best anemometers the market has to offer. However, the recently released Advanced X anemometer from Thies CLIMA can be said to come in the footsteps of BARANI DESIGN's MeteoWind® 2, which is arguably wind resource assessment market's best anemometer and wind vane combo. The adoption of RS-485 MODBUS communication with user selectable RTU or ASCII output and a body/bearing heater with exactly 25W can be read right out of MeteoWind's data sheet. Could this be a reaction of a well-established player in the wind resource assessment industry to a new challenger? 

BARANI DESIGN Technologies is known for their innovation and product quality. Let us wait and see whether they can take the lead away in anemometer design. If Thies CLIMA copies the MeteoWind® 2 configuration, the answer will be clear.

TECHNICAL NOTE: A combined wind sensor integrates an anemometer together with a wind vane. MeteoWind® 2 is able to meet MEASNET wind speed accuracy and linearity requirements with an integrated wind vane, while all other MEASNET capable anemometers are able to achieve MEASNET linearity and accuracy only in a stand-alone configuration.

In 2017, when MEASNET/61400-12-1 Edition 2.0 was approved, the Elliptic Anemometer had been around for at least 4 years and MeteoWind® 2 for at least a year and both were excelling and passing MEASNET linearity requirements at MEASNET's favorite wind tunnel, Deutsche WindGuard GmbH.  Why did MEASNET choose to ignore these wind speed and direction sensors in their Edition 2.0 update?

Arguably, data quality from a wind sensor that measures wind speed and direction together at a single point like MeteoWind® 2 is of higher quality than that from separate wind speed and direction sensors connected by tubes and separated by trusses of lattice towers, as is the status quo with current First Class or Class 1 anemometers. 

Outdated MEASNET mounting requirements of anemometers and wind vanes on lattice towers for wind energy assessment state that the wind vane must be at least 1.5 away from the anemometer.

Does this mean that IEC 61400-12-1: 2017 Edition 2.0 is already outdated at the time of publishing since it did not take into account existing technologies? Is MeteoWind® 2 an exception? Since it is a single instrument, the 1.5 meter rule does not apply.

MODBUS

BARANI DESIGN has been at the forefront of the adoption of robust and proven RS-485 MODBUS communication interface for the meteorological & wind resource assessment industries. Its anemometers and wind vanes have featured this common and highly reliable interface since 2008 and offer a very high level of data reliability and protection against lightning damage. Both companies incorporated user selectable MODBUS RTU and MODBUS ASCII protocols.

POWER CONSUMPTION & VOLTAGE RANGE

MeteoWind anemometers feature the lowest industry-wide power consumption of any MODBUS anemometer on the order of 4.5 mA for wind speed and wind direction combined.  Thies Clima Advanced X anemometers have one of the highest power consumptions, averaging 40 mA and peaking at 100 mA, which is 10 x and 20 x higher than the power consumption of MeteoWind®. Advanced X anemometer voltage range is 3.7 V to 48 V while MeteoWind 2 range is 5 V to 24 V.

HEATING

Both anemometers feature 25 W of body heating, while MeteoWind® offers user selectable heating profiles for solar powered 12 V or 24 V applications where the heater can be controlled not only by the anemometer body temperature, but also by wind speed, thereby eliminating the need for intelligent heater control on the data logger.

WIND SPEED 

Both anemometers feature optimized aerodynamics and mechanics for applications in high turbulence environments and feature minimal over-speeding, and very low starting speeds. Thies Advanced X has passed the full IEC 61400-12-1:2017 Edition 2.0 classification while MeteoWind® 2 full classification has not yet been performed. MEASNET calibrations of MeteoWind® 2 anemometers are performed on a regular bases per customer requests.

WIND DIRECTION

Only MeteoWind® 2 is able to meet MEASNET linearity requirements for wind speed while simultaneously and accurately measuring wind direction to better than 2° accuracy without a dead spot.

AIR DENSITY COMPENSATION 

Thies Advanced X anemometer now features an internal air pressure sensor, while an air pressure sensor was last seen on the Elliptic Anemometer II, the predecessor to the MeteoWind® from BARANI DESIGN. Why did BARANI DESIGN remove the internal pressure sensor from its anemometers?

Aerodynamic effects are governed by the simple Reynolds number equation which, when applied to anemometer behavior, means that if an anemometer behaves linearly throughout the required wind speed range and beyond at one air density, variations in air density and air temperature will not affect its linearity and accuracy. Temperature will only affect bearing friction which at speeds above 4 m/s is negligible. In the case of an anemometers with body heating like MeteoWind® 2 and Advanced X, the air temperature effect becomes negligible throughout the whole wind speed range. 

IS MEASNET/IEC 61400-12-1:2017 EDITION 2.0 NECESSARY?

Edition 2.0 for the year 2017 and beyond creates a new set of requirements for anemometer manufacturers to meet. But are these requirements just extra bureaucracy to fend off emerging anemometer competition or do they really help improve wind data quality over IEC 61400-12-1:2005 from the year 2005?

New requirement for 5 anemometers to be field tested. A larger sample size is always of benefit when compared to the IEC 61400-12-1:2005 requirement of field testing just a single unit.

The new requirement for anemometer wind tunnel testing at different densities and different air temperatures seems redundant when the MEASNET linearity requirement is already well defined and very strict. This new requirement is simply bureaucracy.  Any aerodynamicist or just a student of basic aerodynamics should know and understand the simple and basic Reynolds Number equation governing the behavior of air. This understanding leads one to realize that, if an anemometer meets the linearity requirements of the original MEASNET IEC 61400-12-1:2005 without internal electronic corrections to its linearity behavior, than these new tests at different air temperatures and densities are completely unnecessary. Makes one wonder why Anemometer X now has an internal pressure sensor to enable corrections for air density and why MeteoWind® 2 is able to work just fine without it?

BARANI DESIGN Technologies will showcase their latest product innovations which will include the MeteoHelix® IoT Pro micro-weather stations, ezMETAR airport and heliport weather station & the new MeteoWind® Compact anemometer with a wind vane and analog output.

BARANI DESIGN has been listed on The Things Network as a certified partner with its MeteoHelix® IoT Pro industrial micro-weather station with LoRa wireless connectivity. Available at a price point of 499 eur, this weather station is an attractive proposition for intalling in areas requiring World Meteorological Organization (WMO) precision and data quality, yet with high risk of theft and vandalism. 

BARANI DESIGN has addressed the concerns of not only agricultural customers but also of meteorological organizations which require installation of professional weather stations in remote areas in every part of the world including Africa, South America, China, India and Russia where security of expensive professional hardware is of major concern. "At this price point, theft and vandalism of weather stations is no longer a concern for professional customers" from the words of Mr. Toth of BARANI DESIGN.

While previously, a wireless weather station of similar data quality was available for over 2000 eur, the MeteoHelix® IoT Pro enables four times the data density at the same cost. This means that even with vandalism of 50 % of the deployed MeteoHelix® network, a Meteorological organization will still retain twice the amount of measurement points than was previously possible at the same price point and data quality.

Orban Zsombor returns back safe and sound despite a mishap due to gale force winds after exploring a caldera situated in Bolivia (near the border of Chile) to find the largest daily temperature amplitude in the world. 

The mountain named “Aguita Brava” is a location marked only on good topographical maps. The barren volcano is close to 5,500 m high with a crater of around 800 m wide and 80 m (260 ft) deep. The bottom of the caldera is situated at 5,320 m (17454 ft) above sea level. A perfect location for his research. GPS: -22.512, -67.796

The temperature inversion in the crater basin is so strong that on this day with still air and no clouds the air temperature rises from -35 °C at ground level to -26.6 as measured in the MeteoShield® Professional only 1.7 m above ground.

The maximum temperature of the day was only +4 °C but felt much warmer in the sun and thin air. The maximum daily fluctuation at this high altitude came to be a staggering 30.6 °C (55.1 °F). 

On the second day of measurements, gale force winds came in.... More details can be found on Orban's blog at the following link:  http://weatherman.opofa.com/2018/07/12/aguita-brava-volcano-mars-on-earth-part-2/ 

What does the word "AUTO" in a METAR message indicate?

• The presence of "AUTO" in a METAR report message indicates a fully automated report with no human intervention.

• Absence of AUTO indicates that the report is either a manual report or an automated report with an observer logged on to the system.
  (The report modifier group which contains the AUTO or COR modifiers does not appear in all reports.)

What does the word "COR" in a METAR message indicate?

• Presence of "COR" in a METAR means that a corrected METAR or SPECI is being transmitted. "COR" report invalidates a previous message and replaces it with a "COR" message.

Can "AUTO" and "COR" be in a METAR message simultaneously?

• "AUTO" and "COR" cannot be transmitted in the same METAR. Logic indicates that if the term "COR" is used, the observation cannot be "AUTO", because someone (observer) is correcting it.

• Any automatic "AUTO" report generating system has no way of knowing that the previous message needs to be corrected since it was generated by the rules programmed into the system.

• If an observer is not monitoring METAR observations from a weather station, than by default, the METAR report messages sent from the weather station must contain the modifier word "AUTO".

• "AUTO" informs the pilot that the system is not being monitored by a human observer and the associated risks.

When is SPECI report generated and what is it?

• SPECI is issued and transmitted when a significant change in weather conditions occurs (deterioration or improvement). Significant change in winds and gusts, visibility, cloud base height or occurrence of severe weather. It can be issued by an AUTO METAR generating system based on ICAO & WMO guidelines.

While professional weather observation systems with automatic METAR report generation have been prohibitively expensive for small airport operators, BARANI DESIGN is about to change that. Known for their innovative sensor designs for professional meteorological applications, Barani Design has set its sights on the private airport segment which makes up over 75% of all worldwide aerodromes. With private air traffic on the rise, the need for an affordable, scaleable, accurate and reliable weather observation system for each airport is becoming a necessity.

Weather is becoming more and more localized and unpredictable. This trend is forcing small airport operators to look for uncertified weather solutions and pilots have to rely on the unofficial weather reports posted on each private airport’s web page to plan their flights since the network of official METAR weather stations is very sparse. This is exacerbated by the bureaucracy involved in certifying a METAR weather observation system and obtaining building permits.

The ezMETAR weather observation system from Barani Design is about to change that. The system is built on proven reliable hardware with arguably the most accurate air temperature and wind speed solution on the market, strong lightning protection and a proven meteorological data logger METARlogGSM at its heart. This wireless solar powered Auto-METAR system enables airport operators to install an ICAO certified sensor suite without the need for special building permits. A pilot program at Slovakia’s JASNA Aerodrome is underway to streamline the certification process under the umbrella of the national Hydro-Meteorological Institute. 

BARANI DESIGN will showcase the ezMETAR solution at Farnborough Airshow 2018 in HALL 3, booth 3418.

BARANI DESIGN Technologies to showcase their helical radiation shield technology which has proven itself to deliver an unbeatable combination of accuracy and sensor protection. Benefits of the worldwide patented helical radiation shield design include not only superior air temperature accuracy in all-weather conditions, but also the benefit of extended sensor lifetime and long-term measurement stability. SIRWEC 2018 presents an opportunity for the world-wide experts in road weather to see this technology in person.

The award winning one-of-a-kind design delivers superior long-term accuracy and significantly increased sensor life compared to all-fan aspirated solar radiation shields used not only in road weather applications but also in aviation weather stations such as found on all major airports. In conditions with snow cover it is able to deliver better accuracy performance than most fan-aspirated shields and can be purchased at one-half to one-quarter of their price. Due to no-moving parts it also offers unbeatable reliability.

Precision can be beautiful. MeteoShield® Professional, a breakthrough in near-surface atmospheric air temperature measurement seems to also be turning heads. The one-of-a-kind patented helical design of a solar shield for weather station temperature sensors won silver and people's choice award in the product / industrial category at the Creativepool Annual 2018 design awards. This year, the Annual saw over 2,000 entries and over 20,000 votes cast for people’s choice award.

MeteoShield Professional® is able to deliver temperature accuracies better than many fan-ventilated radiation shields without the need for a fan. Offering an unsurpassed combination of accuracy and reliability makes it ideally suitable for automatic weather observation systems (AWOS) and automatic weather stations (AWS). "It is the most affordable solution for accurate atmospheric air temperature measurement" in the words of designer and BARANI DESIGN Technologies founder & CTO, Jan Barani.

Based on this helical design, MeteoHelix IoT Pro micro-weather station was also awarded the silver prize as part of SURVIA's Grand Prize winning precision agriculture solution at TECHAGRO 2018. 

One of the driest places on earth, situated 5000 meters above sea level with a barren landscape reminiscent of Mars is not a place for vacationers nor any livings things. Yet one man's quest for science will soon bring him to this extra-terrestrial Atacama Plateau between the border of Chile and Bolivia.

Obsessed by exploration from a young age, he is not a typical tourist, nor does he pick the typical vacation spots. It is not a coincidence that his first research adventure landed him in the middle of nowhere to challenge Mongolia's lowest temperature on record, a staggering -55.6 °C, from a little know desert village named Zuungobi. It is the coldest desert village in the world outside of Antarctica. 

After months of meticulous research in the WMO (World Meteorological Organization) database, Orban found his second vacation spot, the Atacama Plateau. A spot known for the clearest air and the highest recorded UV index... he makes sure to pack sunscreen. As a seasoned meteorological observer of the Romanian Meteorological Administration he has a trained eye for finding weather extremes. His research is planned for 6 - 7 days of continuous measurement with a data logger and temperature sensor housed inside a helical radiation shield donated by BARANI DESIGN Technologies. Other supporting sensors will include a meteorological alcohol thermometer and digital precision thermometer. 

He is aware of the dangers that lie ahead. "I will travel alone, unsupported. Some of the days I will sleep outside, nearby my small meteo station at over 5,000 m, therefore it needs good planning and proper acclimatization. I will take with me mainly dry foods and thermoses for keeping the water liquid in the freezing nights. Very few animals are living in this high desert ecosystem, it means predator attacks are unlikely. The lack of water and oxygen will be the main difficulties, the cold and the UV only secondary, as those can be fenced off by proper clothing/ sheltering."

More details about Orban Zsombor's quest to find earth's climate extremes can be found on his blog website: The Exiled Weatherman

Outdoor air temperature sensors (OAT) should possess the following qualities:

• Robustness - radiation shield mount should ideally be made of corrosion resistant metal for strength and longevity and white in color to prevent overheating of the OAT sensor on sunny days.

• Easy mounting - sensor and radiation shield mount should permit easy pole mounting and wall mounting. The mount should position the OAT sensor at least 8 inches (20 cm) from the mounting surface or wall.

• High-quality radiation shield - quite a bit of money can be saved on temperature sensor cost by spending a little extra on a very good radiation shield. A high-quality radiation shield is especially important on hot sunny days since it determines the air temperature a sensor will measure.

The trade-off between high-cost or a high-quality OAT sensor lies in the understanding that a temperature sensor will measure temperature only of air inside the radiation shield. In low-quality shields, even the most accurate and expensive sensors will measure unrealistically high air temperatures due to influences of wall heat radiating onto the shield or due to heating from direct or reflected sunlight. 

Overall system savings can be maximized by using a helical solar shield as written about in Meteorological Industry News and HVAC & Refrigeration Insider®.
