Relationship of precipitation intensity in the form of snow with atmospheric electricity and radiothermal radiation of the snow cover

Abstract

Remote radiophysical methods using artificial satellites of the Earth allow to determine physical and chemical parameters of the atmosphere. For this purpose, calibration subsatellite measurements are necessary. One of the natural phenomena to be studied is precipitation in the form of snow. This paper presents the results of ground-based measurements of radio-thermal radiation of snow cover at two wavelengths 0.88 cm and 1.35 cm, as well as the results of measurements of the variation of the vertical component of the surface atmospheric electric field strength during snowfall. The measurements were made near the ice-water phase transition temperature. The research site is located in the city of Chita (Russian Federation). A strong influence of air temperature on the measured values, especially at the ice-water phase transition temperature, was found.
