**AFWA Shared Processing Site Update**

**Nov 01 Shared Processing Operations Steering Committee**

## 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 [1]

## 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 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] 

**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] 

**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] 

**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

**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

**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

**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

**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**
