1. GPSRO Data Processing and Redistribution at NESDIS Jim Yoe NESDIS/ORA 2 nd 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. InputDataInputData CDAAC CDAAC NESDISNESDIS GTS JCSDA/NCEP ECMWF CWB UKMO Canada Met. JMA BUFR Files file / sounding 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 POCJames.G.Yoe@noaa.gov

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
