1. NOAA NPOESS PREPARATION ACTIVITIES Gene Legg Office of Satellite Data Processing And Distribution Asia Pacific Satellite Data Exchange and Utilization Meeting, Montreal, Oct 10-12, 2007

2. NPOESS Data Exploitation Tasks: Coordinate NPOESS data utilization activities across NOAA Disseminate NPOESS Data Records (xDRs) Provide NPOESS xDR format conversion software Generate and disseminate repackaged xDRs (versions of the xDRs in alternative formats and views) Generate and disseminate NOAA-unique products (augmented environmental products constructed from NPOESS xDRs) Deliver NOAA-unique products to NOAA Long Term Archive (CLASS) Provide services to customers, including a Help Desk, NDE product training, support for product enhancement requests http:// projects.osd.noaa.gov/nde /

3. Examples of NPP/NPOESS NOAA Unique Products Compressed radiance data from CrIS/ATMS (Spatial, Spectral and EOF data reductions) Sounder products for National Weather Service WFOs Radiation budget parameters (e.g. OLR) from CrIS Blended Snow Products from VIIRS, ATMS and CMIS and GOES Blended Ozone products from CrIS and OMPS Vegetation – deliver weekly or biweekly global map of green vegetation fraction and leaf area index, drought index, vegetation health Hazard Geographic Information System (GIS) products – Smoke, Fire, Aerosols, Flash Flood, Precipitation Coastwatch Products of Ocean Color, Coral Bleaching and SST Blended Ocean Products – Color and Altimeter, and/or Winds Microwave-only products from ATMS (temperature, moisture, cloud liquid water, precipitation, rainfall rates, surface emissivity, snow/ice) Daily global, regional maps (gridded data) of all EDRs and SDRs for the science community and for validation

4. NOAA Satellite Operations Facility (NSOF) Located at the Suitland Federal Center, Maryland Houses NPOESS’ Mission Management Center, IDPS, Cal/Val Processing System and the NOAA Environmental Satellite Processing Center (NOAA Central) Final transition/consolidation of ESPC ongoing (SAN) MMC Installed; IDPS installation ongoing (October/November)

5. NPOESS Preparatory Project: IPO-NASA Risk Reduction Demo NPP Spacecraft contract awarded to Ball Aerospace – May 2002 Instrument Risk Reduction » »Early delivery / instrument-level test / system-level integration and test VIIRS - Vis/IR Imager Radiometer Suite (IPO) CrIS - Cross-track IR Sounder (IPO) ATMS - Advanced Technology Microwave Sounder (NASA) OMPS – Ozone Mapping and Profile Suite (IPO) » »Provides lessons learned and allows time for any required modifications before NPOESS first launch Ground System Risk Reduction » »Early delivery and test of a subset of NPOESS-like ground system elements » »Early User Evaluation of NPOESS data products » »Provides algorithms / instrument verification and opportunities for instrument calibration / validation prior to first NPOESS launch » »Allows for algorithm modification prior to first NPOESS launch Continuity of data for NASA’s EOS Terra/Aqua/Aura missions

6. Sensor Update - VIIRS Ambient Testing in Progress – 80% Complete. Estimated Completion Date is Oct 28 Power Anomalies Observed on S/C 28v bus, Investigation Ongoing Fix for Cross-Talk on VISNIR and SWMIR Implemented. Results Under Investigation (Look Promising) Performance Waiver Risk Assessment complete. No actions or concerns for: » »Band to Band Registration » »Half Angle Mirror Sync (scan velocity) » »Dynamic Range Optical cross-talk anomaly investigation continues » »IFA (Integrated Filter Assembly) modifications proposed » »Decision in November Stray light performance accepted for FU1, but trade study for FU2 Structural Cyroradiator » »Decision to add Cold Stage Launch Lock Strain Gauges

7. Sensor Update - CrIS FU1 delivery scheduled for May 2008 Frame/Structure Fault to be mitigated by: » »Reduced test loads » »Improved shear panel (Steel vs AlBeMET – Aluminum/Beryllium composite) and shoulder bolt » »Strengthened frame design effort continues as a back-up OMA (Optic-Mechanical Assembly) completed all testing; ready for integration SSM (Scene Selection Module) delivery delayed until late Oct to fix RF connector anomaly PCE (Processing & Control Electronics) delivery now mid-Oct; replacement of shorted backplane connectors Team working to define acceptable EMI specification relief (waiver) and risk mitigation

8. Sensor Update - ATMS 83GHz and 92GHz Gunn Diode replacement » »Pre-EDU performance is acceptable 57GHz Gunn Diode Replacement » »Hittite and doubler diode reliability a concern; Alternate designs/additional tests in review IF development issues: » »Due to new chip developments utilizing three cutting edge MMIC technologies - » »lnP HEMT, GaAs SVD, and GaAs HEMT may not meet design requirements

9. Sensor Update - OMPS Received Limb Profile re-manifest authority to proceed Completed stray light testing on Nadir Profiler; initial tests indicate the NP bandwidth exceeds the 1.0 nm requirement at 1.1-1.2 nm; No impact to performance Nadir Diffuser Reflectance Degradation » »Root cause – outgassing from epoxy tape on Stray Light (SL) baffles » »Remove, bake-out and reinstall SL baffles (complete) » »Clean Nadir Diffusers (complete) Nadir Profiler completed calibration tests The brass board main Electronics Box (MEB) was integrated to the Limb sensor » »Completed risk reduction EMI/EMC testing » »Limb vibration tests completed successfully
