Abstract: Using a new type of terrestrial laser scanner (TLS), which is particularly suited for measurements of snow covered surfaces, we monitored snow depth, snow water equivalent (SWE) and melt rates in a high alpine catchment during the Winter 2007/08 ablation period. For the first time the spatial variability of these quantities and its temporal development could be studied with a high spatial resolution (cell size 2.5 m). A very high variability of snow depths ranging between 0 - 9 m at the end of the accumulation season was found. This variability decreased during the ablation phase. Average daily melt rates were between 15 mm SWE at the beginning of the ablation period and 30 mm SWE at the end. The spatial variability of the melt rates increased during the ablation season and could not be explained in a simple manner by geographical or meteorological parameters.
