  1. GPSRO Data Processing and Redistribution at NESDIS Jim Yoe NESDIS/ORA 2nd GPSRO Data Users Workshop Lansdowne, VA August 22-24, 2005

  2. Outline • Traditional NOAA Satellite Data Processing & Distribution (SDPD) • GPSRO Data Processing • Status • Issues • Summary – see Issues

  3. Traditional NOAA SDPD • NOAA POES, GOES, etc. • NOAA/NESDIS Office of Satellite Operations • NOAA/NESDIS Office of Satellite Data Processing and Distribution • Satellite data geolocated, operationally calibrated, Level 1 and higher order data produced and distributed to users • 24 x 7 operational activity • NOAA Office of Research & Applications • Calibration, product development, validation, apps. • NOAA/NWS/NCEP, JCSDA, & other users • NWP, analysis, nowcasting, etc.

  4. GPSRO • Satellite operations – external • by EUMETSAT, COSMIC, etc. • SDP – external • METOP/GRAS SAF • CDAAC • Left to NESDIS • Distribution within, and possibly beyond NOAA • For BUFR’ed data (neutral atmosphere) no significant additional processing performed • Science feedback role remains

  5. JCSDA/NCEP Input Data NESDIS CDAAC ECMWF CWB GTS UKMO BUFR Files file / sounding JMA Canada Met. Plan for COSMIC Data Flow: Status: Automatic CDAAC to NESDIS delivery established 8/18/05

  6. Short-term Issues (1) • Getting GPSRO (CHAMP and COSMIC) from NESDIS to NCEP “tanks”

  7. Dennis Keyser

  8. “Data Mining at NCEP” • EMC learns of a new data source • EMC makes a request to NCO • Prioritization • NCO decodes it, then encodes it into BUFR (NCEP-flavored) in developmental database • EMC performs a “sanity check” on the data • NCO moves it into operational database Dennis Keyser

  9. Short-Issues (2) • Putting GPSRO (i.e. COSMIC, possibly CHAMP) on GTS for wider dissemination • Necessary for end-to-end system testing • Addressing formal requirements, process • James.G.Yoe@noaa.gov as POC

  10. Longer-term Issues • Distribution of COSMIC ionospheric data products • “COSMIC II” - Operational • 90% will not be acceptable • Role of UCAR – specifically CDAAC • Will NESDIS need to develop full SDPD capability? • Ionosphere data
