Can rain affect the readings from my Sonic Anemometer?
Very specific rainy conditions can affect the readings from your Sonic Anemometer. Due to the nature of sonic technology, drops of fairly cold water or large amounts of rain may appear to the sensor to be different densities.
Such rain conditions can interfere with the sampling of the wind. The characteristics of these errors are a 180° rotation of the measured wind angle and a very strong increase of the wind speed, reaching towards 40m/s, for short periods of time.
