MICROWAVE EMISSION BEHAVIOUR OF SNOW

The brightness temperature of snow-covered terrain was monitored throughout the w inter of 1984-1985. Radiometers operating at 1, 16,5, and 37 GHz (vertical and horizontal polarization) were used. The snow conditions v aried from fine-grained to refrozen snow and from dry snow to wetnesses of different levels. The effects of snow water equivalent, liquid water content, structure, and grain size were examined in a detailed manner.
