AFWA Shared Processing Site Update

Nov 01 Shared Processing Operations Steering Committee

Captain Robert Wacker

HQ AFWA/XORS

29 Nov 01

overview
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
dmsp constellation status 2
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
dmsp f16 latest developments
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
afwa spp product transition status 1
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
afwa spp product transition status 2
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
afwa spp product transition status 3
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
npoess centrals tim
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
geostationary feature track winds status
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
eos data acquisition
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
updated insat requirements
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
