The paper presents an electrodynamics model of microwave emission of the “ice sheet – snow-firn layers - atmosphere” system. The model is adjusted for the real characteristics of snow-firn cover of the Antarctica, including stratification and structural properties of each layer (ice crusts, density, mean ice grain size, their dispersion, wetness, etc.). The model also considers the effects of microwave scattering by ice grains (Mie scattering). The model brightness temperatures for different regions of Antarctica (dome, zone of katabatic winds, coastal zone) agree well with SSM/I and SSMI/S data. As model input parameters (air temperature and physical and structural layer properties) we used the data of a Swedish-Japanese expedition of 2007/2008 that took place in the vast territory of Dronning Maud Land.
Keywords: Antarctica, snow-firn layers, brightness temperature, model of microwave emission
