Abstract

A method is presented to extrapolate the snow coverage from the visible areas of an elevation zone to areas obscured by clouds. The satellite images are combined with the so called Snow Cover Units (SCU). These are obtained by overlaying features such as ground properties, regions of similar snow accumulation, elevation, exposition and slope. The effect of the mentioned factors on the seasonal decrease is demonstrated in three Alpine basins. The method enables partially cloud covered scenes to be used for high resolution snow cover mapping from Landsat-TM and SPOT-XS data.
