Features of the interaction of microwave radiation with snow cover are investigated to clarify the methods for evaluating the spatial distribution of snow cover. For local conditions the approaches to modeling of changes in the surface brightness temperature depending of the snow cover structure are developed, the causes and possible values of the errors are identified. Comparative characteristics of spatial and temporal variability of the model, satellite and surface data are held for key areas of the East European plain. The similarity of the fields of satellite brightness temperatures, the actual surface air temperature and snow depth are estimated.
Keywords: microwave radiation, dielectric model, brightness temperature, satellite data, stratigraphy a snow cover, existential variability
