  1. 3. Future Program GPM Global Precipitation Measurement

  2. From TRMM to GPM 3. Future Program NASA, JAXA and NICT International Cooperation Mission Cooperation(Expected partners) ： NOAA(US),NASA(US),ESA(EU), CNES/ISRO(France/India) and others

  3. GPM Overview 2 satellites 8 satellites 3. Future Program • Mission: Core Satellite • Observation of rainfall with more accurate and higher resolution • Adjustment of data from constellation satellites Constellation Satellites • More frequent Observation GPM • Global Observation every 3 hours ↓ • Earth heating Phenomena • Study of Climate Change • Improvement of forecasting system *DPR=Dual Frequency Radiometer 14GHz KuPR and 35GHz KaPR

  4. GPM project status 3. Future Program • Core satellite: • GPM core launch schedule was slipped to June 2013 because of NASA budget problem • Currently JAXA is in phase B. • JAXA proceed to phase C/D in JFY 2007. • Constellation satellites: • A lot of changes! • EGPM : disappeared • NPOESS : scale downed (reduced time orbit and CMIS) • NASA constellation : Non-sun synchronous (inclination 40°) etc. • Microwave radiometers get fewer at the operation period of GPM core. It is very difficult to achieve our objectives. We started to use not only microwave radiometer but also microwave sounder data for precipitation map.

  5. GPM Related Meetings 3. Future Program • Workshop: • The 6th GPM International Planning Workshop, *Date: 7-9 November 2006 *place: USA

  6. 3. Future Program GCOM Global Climate Observation Mission

  7. GCOM System Overview 3. Future Program

  8. GCOM-W 3. Future Program AMSR2 Targets of GCOM-W/AMSR2 are water-energy cycle. AMSR-2 will continue AMSR-E observations (water vapor, cloud liquid water, precipitation, SST, wind speed, sea ice concentration etc.). If GCOM-W2, W3 has scatterometer, GCOM-W scatterometer in afternoon orbit will increase time resolution and data coverage in combination with the METOP/ASCAT in morning orbit (to achieve every 6 hours observation).

  10. GCOM-C 3. Future Program Shortwave (SW) & thermal infrared (T) scanning radiometer Targets of GCOM-C/ SGLI is surface and atmospheric valuables related to carbon cycle and radiation budget. SGLI will follow almost of the GLI observations (sea surface temperature, ocean color, aerosols, cloud, vegetation, snow/ ice, and so on). The new SGLI features (250m (VN) and 500m (T) channels and two polarization/ multi-direction channels (P)) will enable to improve land and coastal monitoring and retrieval of aerosol over land. Polarization muti-angle radiometer (P) Visible & near infrared (VN) push-broom radiometer
