  9. QuikSCAT MGDR-lite within NWS NAWIPS NOAA/NASA Winds Workshop

  10. AWIPS Scatterometer Winds Product • Reduced set of 14 field variables derived from MGDR product. • Only points with valid wind retrievals included. • Field variables are BUFR encoded. • Single file contains multiple BUFR bulletins, arranged by region. • Each BUFR bulletin is preceded with a NWSTG flag field separator and WMO header.

  13. QuikSCAT AWIPS Deployment Milestones • Testing and Operational deployment – 10/6 – 12/12/03 (all AWIPS sites currently receiving AWIPS winds) • OB3 installed at first few beta WFO’s – 1/8/04 • Full deployment 3/1 – 7/1/04 (OB3 installed on 130 remaining sites) NOAA/NASA Winds Workshop

  18. WindSat Status • Operational processing at FNMOC • Distribution via shared processing (similar as SSM/I) • SDRs and EDRs • NOAA and NRL retrievals • Initial cal/val completed • Research/operational mission NOAA/NASA Winds Workshop

  19. ASCAT Preparations • MetOp-2 satellite in last stages of testing • Launch scheduled for April 2006 NOAA/NASA Winds Workshop

  20. ASCAT Mission Highlights • ASCAT will employ two sets of three antennas to make observations in two 500 km wide swaths, on each side of the satellite ground track. • Advanced Scatterometer (ASCAT) products will provide two swaths of wind vectors simultaneously at a resolution of 50 km and, on an experimental basis at 25 km resolution. NOAA/NASA Winds Workshop

  21. NESDIS ASCAT Mission Goals To produce wind retrievals in 25 km resolution Wind Vector Cells on an orbit by orbit basis within three hours of data observation 85% of the time. NESDIS will produce a suite of NRT ASCAT products similar to the suite produced for QuikSCAT. Operational processing to begin in late 2006 NOAA/NASA Winds Workshop

  22. Conclusions • QuikSCAT NRT processing since Feb 2000 consistently meets NOAA’s three hour mission requirement 85% of the time. • QuikSCAT AWIPS product successfully integrated into the operational processing stream. • Additional wind products such as 25 km ambiguity and, high resolution, 12.5 km products have been added in 2004. • Preparations for NRT WindSat EDRs underway • Planning for ASCAT mission has begun.
