Abstract
Results of the tropospheric thermodynamics monitoring on the base of multichannel microwave radiometric system “Microradcom” are presented in the paper. The system includes 4 microwave radiometers with the frequencies of 53–58 (6 channels), 56.6 (scanning), 22.235, and 37 GHz, a dopler radar for liquid precipitations measurements, and video system for cloud observations. Passive microwave system provides continuous unattended measurements of the tropospheric temperature profiles in altitude range 0–10 km, and also integral water vapour (IWV) and integral liquid water (ILW). Observations were provided in Dolgoprudny, Moscow region, from 1 March 2012 up to 31 December 2012. The comparison between radiometric and radiosonde measurements shows almost no bias, but a considerable scatter. The scatter is most probably due to radiosondes drifting away from an upright flight route.
