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
