Abstract
A method of detecting precipitation with a sodar apparatus that transmits sound beams into the atmosphere, detects echoes returned from the atmosphere, from the echoes determines a Doppler-shifted spectrum comprising the relative strength of the echoes at various Doppler-shifted frequencies, and estimates wind speed and direction. The method includes automatically estimating the presence of precipitation based on the Doppler-shifted spectrum.
