South Col Ultrasonic Anemometer WMT700

During the 2011 expedition, a prototype replaces the sensor installed during 2008 expedition. A prototype (LSI-Lastem) to support with other two sensors manufactured by VAISALA: WMT700 and WA15D7B. The WMT700 sensor is a robust and reliable ultrasonic anemometer. It measures surface wind, which is one of the key parameters for meteorology and aviation. The WMT700 series uses ultrasound to determine horizontal wind speed and direction.

Lineage

In 2008 at South Col the CombiSD DNA022 sensor (LSI-Lastem, Italy) was installed. During the 2011 expedition, this sensor was replaced with a prototype (LSI-Lastem) to support with other two sensors manufactured by VAISALA: WMT700 and WA15D7B. The WMT700 sensor is a robust and reliable ultrasonic anemometer. It measures surface wind, which is one of the key parameters for meteorology and aviation. The WMT700 series uses ultrasound to determine horizontal wind speed and direction. The measurement is based on transit time, the time it takes for the ultrasound to travel from one transducer to another, depending on the wind speed. The transit time is measured in both directions for a pair of transducer heads. Using two measurements for each of the three ultrasonic paths at 60° angles to each other, the WMT700 computes the wind speed and direction. The wind measurement is calculated in a way that completely eliminates the effects of altitude, temperature and humidity.
