The active layer of the arctic tundra soils temperature sounding on the basis of L-band radiometric observations

Possibility of remote sounding of temperature in the frozen active layer on the North Slope of Alaska was investigated with the use of SK SMOS microwave radiometer on a frequency of 1,4 GHz. It is shown that the soil temperature, sounded with the SMOS, with an error of 2,4 ˚C coincides with the average temperature of the soil in a layer of 0,27 m.
