AB: The Global Precipitation Measurement (GPM) Mission is an international satellite mission to unify and advance global precipitation measurements from a constellation of dedicated and operational microwave sensors. The GPM Core Observatory, which will serve as the calibration standard for the constellation sensors, is scheduled for launch in June 2013. The mission is to provide the next-generation global precipitation products for scientific research and societal applications including quantitative precipitation estimation (QPE) and quantitative precipitation forecast (QPF). Space-based precipitation measurements, when used with contemporaneous analyses of the atmospheric state, can provide a wealth of information about moist physical processes, whose representation is a major source of uncertainty in numerical models used for precipitation forecasting. GPM will deliver global precipitation estimates of unprecedented measurement accuracy, temporal sampling, and spatial coverage, offering new opportunities to pursue innovative usage of these data to diagnose and correct deficiencies in model physics. This presentation will give an overview of the GPM Mission and its science plans, with a focused discussion on how space-based precipitation information can be used to improve model physics within the general framework of data assimilation and statistical parameter estimation to advance precipitation analysis and forecast skills.
