Under the Polar View initiative, Kongsberg Satellite Services (KSAT) have been providing snow melt maps for Norway and Sweden, as well as snow cover maps for Eurasia, for the last 18 months.
The Environment Agency has issued a flood warning for the River Clyst, saying it had "responded to today's rainfall and snow melt", and with rain forecast throughout the day it could rise further.
Using satellite-based snow melt maps supplied by the European Space Agency (ESA) backed program Polar View, herders are able to view the depth of snow and judge where the best foraging spots are to take their reindeer.
These changes may have resulted in earlier snow melt and exposure of darker rocks, soil and sea ice, leading to warming throughout Greenland in the late 19th and early 20th Centuries when soot levels were at their highest.

The Flood Protection Association said compacted snow and ice would melt more slowly than snow on the ground.
When snow or ice melt, they are replaced by darker melt-water pools, land or sea.

While earthquakes have often been blamed for rock failures and landslides on mountain slopes, scientists also point at global temperature rises for rapid thawing of snowfields and glacial melt that can disturb the flow of snow-fed rivers.
During the dry period, a large part of the energy supplied by radiation is used to sublimate snow or ice and therefore, energy available for melting is low, which leads to low melt rates.
The study in Nature Geoscience also asserts that the cool melt water layer may limit the amount of water sucked from the oceans that falls as snow on Antarctica.
