Abstract

The work presents the results of long radiometric measurements of the atmosphere in the city of Chita during the winter period at a frequency of 34 GHz. The power of thermal radiation was also recorded in the thermal infrared range (7…14 μm). Simultaneously with the readings of the brightness and radiation temperature, meteorological parameters of the atmospheric ground level layer and illumination were recorded. As a result, an increase in the value of the radiation temperature in the IR range by 20 K and up to 1 K at a frequency of 34 GHz was detected during the freezing of fog at an ambient air temperature in the surface layer of -25 °C. In addition, variations in atmospheric thermal radiation were detected during cloudiness and pollution with soot aerosol particles
