Vaisala has received a significant order for ultrasonic wind sensors from the National Weather Service of the United States as part of its nationwide surface observation system
The order includes several hundreds ice-free Vaisala Ultrasonic Wind Sensors, including a power supply unit and other accessories.
The order value is over US$4M and the deliveries will take place in 2005.
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.
