Results of study of liquid water in thin clouds and mist with the multichannel microwave radiometric system “Microradkom” are presented in the paper. The system includes 4 microwave radiometers: multichannel with frequencies of 53-58 GHz (tropospheric temperature profiling); scanning 56.6 GHz (atmospheric boundary layer temperature profiling); 22.235 GHz (with a sensitivity of 0,04 K at 1 s integration time for integral water vapor measurements); 37.5 GHz (with a sensitivity of 0.02 K at integration time of 1 s for integral liquid water measurements), and automatic meteostation and video system for cloud observations. Observations were provided in Dolgoprudny, Moscow region, from February 2012 to January 2014.
