The Vaisala Ultrasonic Wind Sensors will be integrated into the Automated Surface Observing System (ASOS), which serves as the primary surface weather observing network in the United States. ASOS is jointly administrated and used by the National Weather Service, the Federal Aviation Administration, and the Department of Defense. The network is designed to support weather forecasting activities, aviation operations, and the needs of the meteorological, hydrological, and climatological research communities.
The Vaisala Ultrasonic Wind Sensor uses ultrasound to determine horizontal wind speed and direction. The wind sensor has three transducers and offers accurate, reliable and continuous data for forecasters and aviation authorities. Accurate information on hazardous wind conditions such as gusts and squalls is crucial, especially for aviation safety.
The special ice-free model of the Vaisala Ultrasonic Wind Sensor will prevent freezing rain and snow build-ups and thus guarantee uninterrupted operations throughout the year.
