Mean annual precipitation was computed based on snow and rain-fall in mm water equivalents from the regional climate model MAR v3.835, using daily 5 km data. The climate model handles redistribution of the winter snowpack through the CROCUS modelling scheme. Surface temperatures were extracted from the satellite based MOD11A1 MODIS product, offering daily data at 1 km spatial resolution. This product was corrected for cloud cover36 to minimize a cold winter bias, and subsequently gap-filled with MAR v3.8 surface temperatures again at 5 km spatial resolution. Only MAR-data from terrestrial areas were used; sea- and glacier-classified areas were omitted.
