Finally, five challenges for future space-based precipitation measuring missions are discussed. GEOSTATIONARY OPERATIONAL ENVIRONMENTAL SATELLITE-R RISK REDUCTION PLAN AS A MODEL FOR NOAA'S GPM STRATEGIC PLAN NOAA's strategic plan for GPM could draw from the NOAA Geostationary Operational Environmental Satellite-R (GOES-R)

Of the activities recommended earlier in this report, examples of interagency activities include the following: • Formalizing and supporting existing coordinating mechanisms between the National Aeronautics and Space Administration (NASA) and NOAA and establishing new mechanisms as needed • Implementing an efficient NOAA-NASA interface for data producer and user feedback, quality assessment, operational readiness, and product distribution • Assigning and supporting GPM readiness as a priority effort at the Joint Center for Satellite Data Assimilation (JCSDA)

1. GPM Core Satellite and Constellation Satellites The array of satellites required for operational global precipitation measurement and mapping can be viewed in an international context as a major component of the World Weather Watch Global Observing System and the Global Earth Observation System of Systems.

(3.4) • Take a leadership role in the international satellite community by proposing specific actions for the accurate calibration of all microwave imagers and sounders through cross-calibration and standard reference data sets and for implementing internal calibrations on all future microwave sensors.

One shortfall is in measurement of light precipitation in mid- and high latitudes. The GPM radar has questionable sensitivity for detection of light rain, thus, its value for validating passive microwave precipitation estimates of light precipitation is uncertain.

contributions as a component of a continuing and evolving international constellation of satellites. In addition, NOAA should pursue efforts within the World Meteorological Organiza tion and the Coordination Group for Meteorological Satellites to strengthen support for an operational program of a global, satellite-based precipitation measurement system.

, and the present constellation of passive microwave sensors in conjunction with TRMM's unique suite of sensors provides an ideal source of global, intercalibrated data with which to refine operational applications in preparation for future precipitation-measuring missions.
