 GRaWAC is an active Frequency Modulated Continuous Wave (FMCW) cloud radar with dual frequencies at 167.3 and 174.7 GHz with Doppler capabilities. GRaWAC can be operated on an aircraft (nadir looking) or from the ground (zenith observations).\\
-At both frequencies, the cloud radar transmits saw tooth frequency chirps. The combination of the two frequencies close to the 183.3 water vapor absorption line enables the retrieval of water vapor profiles with the Differential Absorption Radar technique (DAR) in cloudy and precipitating conditions.\\
