Abstract :
The radio acoustic sounding system (RASS) is a method of remotely measuring atmospheric temperature profiles by combining acoustic and radar techniques. This method has been applied to wind profiler radars in Colorado, and excellent performance in both height coverage and accuracy has been obtained. Various acoustic source functions are examined, and it is shown that FM-CW acoustic signals are less susceptible to error than pulsed acoustic systems when using pulsed radars for RASS. The remotely determined temperature profiles are compared with co-located radiosonde soundings, and good agreement is found
