Abstract :
The response of the SSM/I microwave radiometer to snow-covered terrain in Finland is investigated using data for the winters of 1996-97, 1997-98, and 1998-99. The effect of temperature to the brightness temperature of dry snow is examined and a method is proposed to reduce snow/soil temperature-caused fluctuations in the brightness temperature. The feasibility of the method is verified.
