Abstract. Snow depth is one of key physical parameters for understanding the land surface energy balance, soil thermal regimes, regional- and continental-scale water cycles, as well as assessing water resources. In this study, snow depth climatology and spatiotemporal variations were investigated using the long-term (1966–2012) ground-based measurements from 1814 stations across the Eurasian continent. Spatially, mean snow depths of >20 cm were recorded in northeastern European Russia, the Yenisey River basin, Kamchatka Peninsula, and Sakhalin. Annual mean and maximum snow depth increased significantly during 1966–2012. Seasonally, monthly snow depth decreased in autumn, and increased in winter and spring over that period of time. Regionally, snow depth increased dramatically in the areas north of 50° N. Compared with air temperature, snowfall had more influence on snow depth and snow water equivalent during November through March across the former Soviet Union. This study provides a baseline for changes in snow cover, which are significant in climate system changes over the Eurasian continent.
