Satellite monitoring over 1982-2015 shows earlier onset of snow melt on Svalbard. The most pronounced shift is in valleys, where the ground is snow-free 1-2 days more every year during summer. Snow cover variability in lowlands correlates with the variability of sea ice in the adjacent seas, especially in June.
2020 was the warmest year on record for Norway since the temperature measurements began more than 120 years ago. For Svalbard, although not beating the record from 2016, 2020 was also a warm year with the warmest summer in the 121-year record for Svalbard Airport. The Norwegian Meteorological Institute conducts in-situ measurements and remote sensing observations of the cryosphere: terrestrial snow cover, permafrost and sea ice. What types of cryospheric observations are available on cryo.met.no for the Svalbard area, and what characterized these for 2020?
