  1. AFWA Shared Processing Site Update Nov 01 Shared Processing Operations Steering Committee Captain Robert Wacker HQ AFWA/XORS 29 Nov 01

  2. Overview • DMSP Constellation Status and F16 Latest Developments • AFWA SPP Product Transition Status • Other current activities: • NPOESS Centrals TIM • Geostationary Feature Track Winds Status • EOS Data Acquisition • Updated INSAT Requirements

  3. DMSP Constellation Status [1]

  4. DMSP Constellation Status [2] • F15 Attitude Control • Precision attitude control provided by 3 gyros • One failed in Sep 01; second showing signs of failure within months • Failure of second attitude gyro would introduce earth-location errors up to 30km in F15 data • F12 and F14 have only a few months' life left on last remaining digital tape recorders • F13, despite age, remains healthy

  5. DMSP F16 Latest Developments • DMSP flies in early-morning (F13) and mid-morning (F12, F14, F15) orbits • F16 slated for early-morning orbit; F17 for mid-morning • F15 attitude control problem now makes mid-morning orbit more likely to lose all operational spacecraft than early-morning orbit • AFWA requested F16 orbit change to mid-morning • DMSP CSAT concurred • Launch currently scheduled for 29 Jan 01 • F16 has same gyros as F15; SMC and NOAA SOCC studying gyro failure mitigation strategies • F13 likely to fail before replacement by F17 in early '04; user community and AFSPC need to advocate for funding of other launch options if F17 needed sooner

  6. AFWA SPP Product Transition Status [1] • DMSP Mission Sensor Data Files • Legacy “prep files” still produced for F12-F15; will discontinue when no longer needed but NLT May 02 (mainframe decommissioning) • New Raw Sensor Data Record (RSDR) files operational now for F12-F15 • Only RSDRs will be produced for F16

  7. AFWA SPP Product Transition Status [2] • Snow Depth Analysis • Legacy format product (SNODEP) will remain operational NLT mainframe decommissioning in May 02 • Interface specs and sample files in new GRIB format have been sent; AFWA resolving format problems with FNMOC and NESDIS • New product will be operational as soon as problems resolved

  8. AFWA SPP Product Transition Status [3] • Cloud Analysis • Legacy format product (RTNEPH) will remain operational NLT mainframe decommissioning in May 02 • Interface specs have been sent; coordinating additional changes now based on feedback • Sample files with higher resolution and in new GRIB format will be sent by mid-Dec 01 • New product will be operational when AFWA CDFS II system becomes operational in May-Jul 02

  9. NPOESS Centrals’ TIM • Centrals found similarities among present-day satellite and projected NPOESS data consumption patterns • Centrals agreed that NPOESS IDPS should provide data management services • Would reduce data latency incurred by data receipt, processing, storage, and retrieval at the Central • Would spare Centrals the expense of duplicating services the IDPS will likely require for its own use • Centrals urged IPO to seek type-accreditation for IDPS to lessen security difficulties

  10. Geostationary Feature Track Winds Status • AFWA Meteosat-5, Meteosat-7, and GMS-5 feature track wind production considered operational by AFWA and FNMOC/NRL • AFWA providing sample GOES data to NRL/UW for GOES "McIDAS-independent" FTW algorithm development

  11. EOS Data Acquisition • AFWA views EOS data, particularly from MODIS, as NPOESS risk reduction • Working with NASA/Goddard and NOAA/NESDIS to receive operational MODIS products • GSFC Rapid Response server and DREN initially • NOAA EOS server and possibly SPN end-state • Initial product request for limited set of MODIS Level-1B and –2 products over Afghanistan AOR • Will grow product request to include more MODIS data as experience and capability grows; will add sounder instruments later

  12. Updated INSAT Requirements • Currently receiving only INSAT-1D imager data • Poor earth-location and 1-1.5 hours latency limits utility • Request NESDIS investigate obtaining: • INSAT-2E CCD data • Imager and CCD data from INSAT-3 series and following launches • Specs for INSAT direct-readout data • More frequent than 3-hourly imagery when available • Timeliness and reliability improvement • Earth-location algorithm for INSAT-1D
