4. Past Years Contributions to CEOS • Contribution, coordination, updates to GEO SBA tasks • Mostly Water and Climate SBA • Support to Mary Kicza, NESDIS AA, in her role as CEOS SIT lead • Input to CEOS PC work plans, etc. CEOS Precipitation Constellation Workshop – Tokyo, Japan

5. Update on GPM Activities at NOAA (1) • PMM Science Team • NOAA continues to provide ~80% support to four NOAA PI’s on NASA’s PMM Science Team • Ferraro – Satellite precipitation over land • Kuligowski – Use of TRMM data to support NOAA/OHD • Williams – Advanced radar measurements • Xie – CMORPH + gauges • NOAA Steering Group (SG) on space-based precipitation • NOAA organizing its satellite precipitation activities through newly formed SG • As per 2007 NAS report • Comprised of NESDIS, NWS and OAR • Provides oversight on R&D (PMM projects), interface with NOAA goal teams (budget and planning process), collaborations with NASA CEOS Precipitation Constellation Workshop – Tokyo, Japan

6. Update on GPM Activities at NOAA (2) • Recent activities with NASA • Periodic meetings to discuss • Programmatics • Scientific collaborations • Algorithm development, especially use of high frequency measurements • Validation, especially NOAA’s Hydrometeorological Testbed (HMT) • AMSU precipitation algorithm improved/time series reprocessed • Used as input into blended algorithms like 3B42 and CMORPH • PMM meetings • Science Team • Working Groups • Advisory panels • Representation at other meetings • 3rd TRMM Scientific Conference • 3rd GPM GV Workshop • 7th International GPM Planning Workshop CEOS Precipitation Constellation Workshop – Tokyo, Japan

7. NOAA Scientists Contribute to Algorithms • Satellite-derived estimates of precipitation are crucial elements of NOAA’s “business model” • Required to meet NOAA Mission Goals • Operational precipitation products • GOES based – NESDIS heritage • Passive MW • DMSP EDR’s • Contributed to land component of NASA’s GPROF algorithm via NASA funded projects • AMSR-E and TMI • NOAA POES/AMSU based • Use of high frequency • Snowfall over land • Established and emerging blended GOES and POES • GPCP w/NASA • CMORPH • SCaMPR CEOS Precipitation Constellation Workshop – Tokyo, Japan

8. NOAA Climate Prediction Center Developing Merged CMORPH – Gauge Analysis • Requirement: Most accurate and detailed precipitation analysis possible • Use gauges where available; bias-corrected CMORPH elsewhere • Daily totals; 0.25° grid • Tested over China for May – September 2007 • Approach: • CMORPH operational: 60°N - 60°S, 30-minute/8 km • Averaged to 3-hourly/0.25 ° grid • Estimate/remove bias • Analyze available gauges • Estimate errors for both gauge and CMORPH analyses • Combine with gauge analysis using Optimum Interpolation August 2, 2007 CEOS Precipitation Constellation Workshop – Tokyo, Japan
