Compact wind sensor meeting the highest MEASNET accuracy requirements. Exceeds WMO and NWS specifications by a factor of 5, thus it can be considered maintenance free for a lifetime in most meteorological applications. Compared to ultrasonic anemometers, it offers faster response time at wind speeds greater than 4 m/s, thus its able to accurately capture even the shortest wind gusts. It has higher data availability that ultrasonic wind sensors in harsh stormy and winter weather.
