The annual and daily courses of the radiation balance of the Earth's surface, the intensity of diffused solar radiation, the intensity of direct solar radiation, downward and upward long-wave radiation fluxes and short-wave radiation fluxes from surface were analyzed and described. Daily values of accumulation and ablation of the snow cover at the Antarctic station "Akademik Vernadsky" for the period 1997-2024 were calculated. Their monthly and annual values have been investigated on homogeneity and stationarity. The description of the seasonal features of accumulation and ablation was carried out. The coefficient of thermal conductivity of snow was assessed as one of the factors that contributes to the physical processes of heat transfer to the underlying surface and the heat balance. The empirical relations between the raw of meteorological parameters, which are measured by the automatic weather station Vaisala AWS-310 (directly measured), and the temperature of the surface and illuminance of the light flux measured by loggers (indirectly measured) were found. These empirical relations were obtained for two types of weather conditions “without precipitation” and “falling of liquid precipitation”. Product Description popup.authors Shchehlov Oleksandr A.
