Abstract: Microwave FMCW Radar is used for automatic remote snow cover profiling in avalanche release zones. The radars are buried in the ground below the snow cover and are therefore not subjected to snow and avalanche forces. Data are transmitted together with additional snow and meteorological parameters by radio to a base station using a commercial logger system. Radar data of the electromagnetic snow cover stratigraphy are converted to a bitmap representation of the stratigraphy or are available as time series of spectra showing reflectivity of snow layers in function of distance from ground. The amount of new snow, snow settlement, fracture height of slab avalanches and meltwater percolation in the beginning phase of snow melt can easily be determined.
