Advances in operational permafrost monitoring on Svalbard and in Norway

Abstract The cryosphere web portal maintained by the Norwegian Meteorological Institute (MET Norway), https://cryo.met.no , provides access to latest operational data and current state of sea ice, snow, permafrost in Norway, Arctic, Antarctic. We present addition this portal: monitoring at MET Norway methods for visualising real-time temperature data. temperatures are compared climatology generated from station’s record, including median, confidence intervals, extremes, trends. There additional weather stations with extended measurement programs these locations. collocated offers daily updated studying state, trends, effects of, e.g. extreme climate events on temperatures. Ground rates obtained long-term records warmer found typically 0.1 ∘ C–0.2 C per decade. In contrast, colder High Arctic Svalbard, a warming up 0.7 decade is apparent. information faster than ever before, potentially assisting early detection record high active layer thickness pronounced increases. It may also become an important cornerstone warning systems natural hazards associated degradation.
