【 摘 要 】

This presentation is to report on the progresses made for the NASA Precipitation Measurement Mission (PMM) science team research tasks that are recently funded by NASA HQ. These tasks include (1) extending the existing GEOS all-sky analysis system to assimilate radiance data from other microwave sensors in GPM constellation satellites, (2) producing improved GEOS analyses of precipitation and downscaling of satellite precipitation estimates, and (3) providing the GEOS analyses to PMM Science team as prototype of GPM Level-4 products.
