Current Status Operational geostationary satellites – USA: GOES-13 (East), -15 (West), GOES-14 spare EUMETSAT: METEOSAT-10 (0 Deg.) & -7 (Indian Ocean); & -9 (R/S), Super R/S experiments with -8 at 2.5 min intervals for limited periods. India/ISRO: Kalpana & INSAT-3D CMA:FY-2E & F; KMA:COMS; Russia:Electro-L N1; JMA:MTSAT-2 Operational polar satellites – Suomi-NPP data being used operationally in NWP centres (ATMS, CrIS rads) with good impacts. METOP-A/B IASI and AMSU-A/MHS data being assimilated. GCOM-W1 (Japan) AMSR-2 proving a good replacement for AMSR-E FY-3C (China) New MW channels at 118GHz. Monitoring shows data are good quality ASCAT and Oceansat-2 providing scatt-derived winds. Cosmic constellation providing GPS-RO bending angles (1 satellite died)

11. 11 Page The GPM Core Observatory satellite was successfully launched on February 27th, 2014. Data from the GPM Microwave Imager (GMI) and Dual-frequency Precipitation radar (DPR) have the following release schedule. All data are freely available through the NASA's Precipitation Processing System at http://pps.gsfc.nasa.gov http://pps.gsfc.nasa.gov June 16th – GMI Level 1 Brightness Temperature data have been released. This includes GMI instrument swath data. July 14th – GMI Level 2 Precipitation Rate data have been released. This includes precipitation rates estimated using the Goddard Profiling algorithm (GPROF14) and are available as swath data. Early September – DPR Level 2 precipitation rate data will be released via PPS and JAXA. This includes three-dimensional swath data from the DPR Ka and Ku band radars. Mid-September - The DPR-GMI Level 2 combined product will be released. December 2014 – NASA’s Level 3 Integrated Multi-Satellite Retrievals for GPM (IMERG) will be released with all available data.
