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 … WebbThe choice of this function is quite arbitrary: the only basis is that there is very little negative freeboard in Arctic sea ice, there is nearly always a snow cover over sea ice and … shannen wilson https://heating-plus.com

Webb31 okt. 2024 · If there is a need for monitoring a number of DIRs, each of an area of perhaps 200,000 km 2, the radar will scan them sequentially, in which case the revisit time may be extended to 10–15 min, which is still adequate to monitor even rapid changes in sea ice conditions. Webb1. 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 … Webb1 jan. 1992 · The Physical Basis for Sea Ice Remote Sensing.
