  1. Preliminary Design Review POES-GOES-GPS Blended TPW Products July ??, 2008

  2. Outline • Team Members • Product Overview • Project Requirements • System Design • Quality Assurance • Documentation • Project Timeline • Issues To Be Resolved

  3. Team Members • Limin Zhao, John Paquette and Stan Kidder • Project Leads • Andy Jones and John Forsythe • Lead Scientists • Ivan Tcherednitchenko • Lead Developer • Peter Keehn • System Implementer • ?????? • User Team(?) • ?????? • POP Lead (?)

  4. Product Overview (1) Total Precipitable Water • TPW Product • Over water: Blended AMSU & SSM/I (Kidder & Jones 2007) • Over land (primarily CONUS): • Primary: GPS PW(Ref?) • Backup: GOES PW(Ref?) 0 mm 75 mm 25 mm 50 mm

  5. Product Overview (2) Percent of Normal TPW • Percent of Normal TPW Product • TPW divided by NVAP weekly normal TPW(Ref?) 100% 200% 0%

  6. Product Overview (3) • Products produced every 6 hr, nominally at 00, 06, 12, and 18 UTC • Map: Mercator, 71°N to 71°S, 16 km resolution at equator • Each product is about 3.5 Mbytes in size (28 Mbytes per day) • Input data: • 5 days of AMSU and SSM/I data (? Mbytes) • most current GPS PW and GOES PW (? Mbytes) • Output data • HDF-EOS format • McIDAS format • AWIPS format

  7. Project Requirements • SPSRB • #9902-19 POES/DMSP Blended Products: Generate operational blended TPW and RR products from POES and DMSP sensors • Others • OSIP 06-084 • NWS OB9 • User requests fromn varous WFOs • NOAA’s Hydrometeorological Testbed (HMT) • NOAA’s Scientific Data Stewardship (SDS) program Proposed products satisfy all requirements

  8. System Design • Products will be generated at NSOF • AIX Machine will host • Input data: • AMSU and SSM/I data acquired from DDS • GPS data acquired from ??? • GOES PW data acquired from ??? • Output data (in ??? format) hosted on DDS • Output fields converted to AWIPS format and distributed by NOAAPORT (???) • (I’m sure I’m leaving things out)

  9. Quality Assurance • By CIRA/StAR/SAB?

  10. Documentation • Document 1—written by ? • Document 2—written by ? • …

  11. Project Timeline (1) • Mar 08: Development Phase Begins • Mar 08: IPT Branch Lead informed to begin product development • Mar 08: Initial Archive Requirements identified • Mar 08: Quality Monitoring Concept Defined • Mar 08: Static test data file provided to NWS/AWIPS (OB9.x) • May 08: Long-term Maintenance Concept Defined • Jun 08: Preliminary Design Review • Jun 08: Development processing system defined • Sep 08: Critical Design Review • Oct 08: Code is prepared for implementation • Oct 08: Final Archive requirements identified • Oct 08: Operational and backup processing defined

  12. Project Timeline (2) • July 08: Pre-operational Phase Begins • July 08: Pre-operational product output evaluated & tested • July 08: Final/Streaming product delivered to NWS/AWIPS • Nov 08: Operational and backup processing capabilities in place • Nov 08: Final IT Security Concept Defined • Jan 09: Code transitions to operations; all documentation is complete • Jan 08: Operational and backup capabilities reach ops status • Jan 09: Brief SPSRB capability is ready to operational • Feb 09: Operational Phase Begins • Feb 09: SPSRB declares product operational • SPSRB Secretaries/manager update the SPSRB product metrics web pages • OSD updates Satellite Products database Back to Index

  13. Issues To Be Resolved • Porting DPEAS to AIX

  14. Backup Slides

  15. Outline • Project Overview (Limin and Stan) • Project Management Overview and Planning (Limin) • AWIPS Requirements (John P) • DPEAS (Andy) • Operational System Design and Development (Limin and Andy) • Processing System Infrastructure (Ivan and Limin) • Products and Validation Plans (Stan and John F ) • QC Monitoring (Ivan and Limin) • Operational Integration and Data Dissemination (Ivan and Peter) • Summary (Limin)

  17. Project Overview

  18. Background • Terminology • Presentations • Requirements • Goals

  19. Terminology • Blended TPW – • Blended TPW Normal – • DPEAS – • GRID - • AWIPS – • McIDAS -

  20. Presentations • PDR • July 8, 2007 • CDR • Sept 2008

  21. Requirements Documentation • NWS requests • SBSRB requirements document

  22. NWS Requirements • Document Title: POES-GOES Blended Hydrometeorological Products • Product specifications / needs: Atmospheric temperature and moisture profiles from IASI, AMSU-A and MHS. • Data Latency: 0.5 ~ 3.0 hrs. • Refresh: per 6 hours (possibly 3 hourly). • Timeliness (e.g., how soon after observation is product needed?): 0.5 ~ 3.0 hrs

  23. Project Goals • Provide users the blended TPW from AMSU, SSMI and GPS. • Provide updated blended products by merging data from more sensors, such as , AMSR-E, TRMM, … • Provide blended RR products

  24. POES/GOES Blended Hydro Products • Blended TPW • Blended TPW Normal • Blended RR
