Thus, Northern Hemisphere snow cover, which comprises approximately 98% of the global total area of seasonal snow, is responsible for the largest annual and inter-annual contrasts in land surface albedo. Here, we examine recent changes in snow cover (2000-2016) in the western mountain regions (hereinafter WMR) of the Kola Peninsula in Arctic Russia, an area that has undergone significant climate change in recent decades. Future changes in snow cover have the potential to have a major socio-economic impact in this region, which is primarily dependent on mining and tourism for its economy. We 15 used a combination of remote sensing data, the first time it has been used to assess snow cover in this region, and meteorological observations in our analysis.
