Experimental data on descending radiation of atmosphere in the resonance absorption band of water vapor 18 - 27.2 GHz

This dataset includes binary files of radiometric measurement sessions 2018-2019. Measurements ofmicrowave descending radiation in the band of resonance absorption of water vapor 18 - 27.2 GHz were performed.The observations were carried out by means of special microwave multichannel (47 channels) radiometer-spectrometer developed in Kotel'nikov Institute of Radioengineering and Electronic of RAS Special Design Bureau.Radiometer was located in Fryazino, Moscow Region, Russian Federation. These data were used for assesing the influence of various weather conditions (cumulus cloud cover / clear sky) on the intensity of fluctuations in brightness temperature of atmospheric descending radiation.For meteorological interpretation, the observation data (values of near-surface air temperature, atmospheric pressure, absolute humidity e t.c.) from two VantagePro2 meteo stations located at a distance of about 300 metersfrom the radiometer-spectrometer were used additionaly (also included in dataset).
