Innovative spiral design of the MeteoShield® Professional begins sea trials on buoys

Marine buoy radiative heating errors to be prevented by the helical MeteoShield® Professional

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.

The future of affordable METAR

The increase in electronics reliability and processing power has enabled us to launch a new ezMETAR AWOS weather station that generates not only Auto-METAR, but also SPECI reports automatically every half hour, wirelessly. Using field proven sensors and LTE/GSM data logger complemented by robust power and lightning protection, affords these ezMETAR systems the promise of revolutionizing small VFR airport operations worldwide with their reliability, affordability and precision, while offering expandability and customizability for even IFR operations. The sensors and data logger can currently be found in operation in all climates and around the world in Africa, Asia, the Americas & Europe.

ezMETAR weather observation system generates Auto-METAR & SPECI reports affordably

The ezMETAR weather observation system will be on display at the World Meteorological Exhibition on June 5 - 7, 2019 in the BARANI DESIGN Technologies stand 6020, which will be held in Hall 4 of Palexpo in Geneva, Switzerland.

Birds’ fight against ultrasonic wind sensors

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.
