The Precipitation Measurement Missions (PMM) science team seeks investigations related to satellite observations of precipitation using measurements from, but not limited to, the Global Precipitation Measurement (GPM) Core Observatory (2014-present), GPM mission constellation partner spacecraft, and the Tropical Rainfall Measuring Mission (TRMM, 1997-2015). This program supports scientific investigations in three research categories: (1) The use of satellite and ground measurements for physical process studies to gain a better understanding of precipitation, the global water cycle, climate, weather, and concomitant improvements in numerical models from cloud resolving to climate scales; (2) development of methodologies for improved hydrological modeling and applications of these satellite measurements; and (3) continued enhancement and validation of GPM and TRMM retrieval algorithms. While the major focus of the expected research should be on GPM and TRMM satellite data products, observations from other satellite, aircraft, and ground sensors may be used for the proposed research.

Deadline: Notice of intent due Apr 30, 2018. Proposal due Jun 28, 2018.
