Abstract :
The satellite Nimbus-7 is mapping the brightness temperature of the Earth surface at several microwave frequencies. Its observations can be applied to the remote sensing of snow cover. In this report the effects of different types of surfaces, such as forests, boglands, farm lands, and lakes are studied. It seems to be possible to determine the water equivalent of a dry snow cover, if the surface effects are taken into account by comparison with observations taken before the snowfall.
