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). While the major focus of the expected research should be on GPM and TRMM satellite data products, observations from other satellites (including Smallsats or CubeSats), aircraft, and ground sensors may be used for the proposed research.

GPM has five Scientific Objectives: (a) Advancing precipitation measurements from space; (b) Improving knowledge of precipitation systems, water cycle variability, and freshwater availability; (c) Improving climate modeling and prediction; (d) Improving weather forecasting and 4D climate reanalysis; and (e) Improving hydrological modeling and prediction. In general, NASA focuses on the research, science, and parameterizations to improve the models listed in (c), (d), and (e) and not necessarily the development or maintenance of forecasting or prediction models.
