Introduction. Trends in sea-ice extent as seen from satellites – rather coarse indicators of the health of the polar ice covers – have been monitored for only three decades (1978-present) (Reference Comiso, Parkinson, Gersten and Stock Comiso and others, 2008).Yet, these satellite estimates have served as the bellwether of climate of the Arctic and, to a …

WebbHere the microwave emission processes from sea ice are simulated using the combination of a one-dimensional thermodynamic snow and sea ice model and a microwave … WebbSince 2008, sea-ice modellers at the AWI have taken part in the international competition for forecasting the Arctic sea-ice minimum. The contest always starts in June, when the Arctic summer settles in and the ice cover begins melting. We use the term sea-ice minimum to describe the smallest area the sea ice shrinks down to before the winter ...

Webb2 sep. 2024 · Seasonal snow cover is the largest single component of the cryosphere in areal extent, covering an average of 46 × 10 6 km 2 of Earth's surface (31 % of the land area) each year, and is thus an important expression and driver of the Earth's climate. In recent years, Northern Hemisphere spring snow cover has been declining at about the …
