DIE STÄDTISCHEN WETTERSTATIONEN FÜR STRASSENBELEUCHTUNGEN, WIE DAS METEOHELIX®IOT PRO, 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

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.

What Benefits Does IoT Bring to the World of Meteorology?

Smart-city weather station for Resilient-cities initiatives

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.

New Meteorological Sensor Technologies at AMS 2020

New technologies at AMS 2020 by Comptus Inc. of New Hampshire.

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.
