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. 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.
