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 … WebbThe physical basis for retrieving precipitation from passive microwave measurements depends on distinguishing the radiation coming from Earth’s surface with the radiation coming from precipitation. This is more difficult to do over land, so we provide estimates over the ocean only. birman cats for sale in ct
