GPSRO Data Processing and Distribution Overview at NESDIS: 2nd User Workshop Insights

This document outlines the key discussions from the 2nd GPSRO Data Users Workshop held by NESDIS in Lansdowne, VA, from August 22-24, 2005. It covers traditional NOAA satellite data processing and distribution methods, GPSRO data processing status, and relevant issues faced by the organization. Key topics include the operational activities of NOAA satellites like POES and GOES, the importance of calibration and validation, and plans for the effective dissemination of COSMIC data. It highlights ongoing and future challenges in integrating GPSRO into operational systems for user access.

  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
