 Abstract: The European Alps are a major mountain range in Europe with a long history of dense in-situ observations of snow cover, whose analysis is hampered by the fragmentation of observer networks and the varying quality and availability of their data. Here we present a collation of in-situ observations of snow depth and depth of snowfall across the whole Alps. We employed novel quality checks and gap-filling procedures based on spatial correlation, which work in areas with a moderate to high density of stations. We show how the climatology of in-situ snow depth and remotely sensed snow cover duration matches the expected climatic forcing zones. These large-scale climatic zones not only influenced day-to-day variability but also long-term trends. A multivariate attribution study highlights the impact of temperature and precipitation variability on snowfall patterns in a smaller subregion. Finally, future snow cover information is derived from an ensemble of regional climate models.
