Abstract The paper presents the results of studies of the brightness temperature of the underlying surface in different natural zones of West Siberia based on the daily data from SMOS (ESA). The effect of change in phenological phases of soil cover and vegetation in the Arctic desert, tundra, forest tundra and taiga on emissivity of the underlying surface is studied by the example of test sites adjacent to research stations of the Siberian Environmental Change Network (SecNet). We investigate the regularities and peculiarities of microwave radiation of the underlying surface in different natural zones of West Siberia depending on seasonal freezing and thawing of the underlying surface as well as on different physical characteristics of permafrost and seasonally frozen soils and vegetation.
