    Asia Pacific Satellite Data Exchange and Utilization Meeting, Montreal, Oct 10-12, 2007

  • NPOESS Data ExploitationTasks:Coordinate NPOESS data utilization activities across NOAADisseminate NPOESS Data Records (xDRs) Provide NPOESS xDR format conversion softwareGenerate 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

  • Examples ofNPP/NPOESS NOAA Unique ProductsCompressed radiance data from CrIS/ATMS (Spatial, Spectral and EOF data reductions)Sounder products for National Weather Service WFOsRadiation budget parameters (e.g. OLR) from CrISBlended Snow Products from VIIRS, ATMS and CMIS and GOESBlended Ozone products from CrIS and OMPSVegetation deliver weekly or biweekly global map of green vegetation fraction and leaf area index, drought index, vegetation healthHazard Geographic Information System (GIS) products Smoke, Fire, Aerosols, Flash Flood, PrecipitationCoastwatch Products of Ocean Color, Coral Bleaching and SSTBlended Ocean Products Color and Altimeter, and/or WindsMicrowave-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

  • NOAA Satellite Operations Facility(NSOF)Located at the Suitland Federal Center, MarylandHouses 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)

  • NPOESS Preparatory Project: IPO-NASA Risk Reduction DemoNPP Spacecraft contract awarded to Ball Aerospace May 2002

    Instrument Risk ReductionEarly delivery / instrument-level test / system-level integration and testVIIRS - 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 ReductionEarly delivery and test of a subset of NPOESS-like ground system elementsEarly User Evaluation of NPOESS data productsProvides algorithms / instrument verification and opportunities for instrument calibration / validation prior to first NPOESS launchAllows for algorithm modification prior to first NPOESS launch

    Continuity of data for NASAs EOS Terra/Aqua/Aura missions

  • Sensor Update - VIIRS

    Ambient Testing in Progress 80% Complete. Estimated Completion Date is Oct 28Power 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 RegistrationHalf Angle Mirror Sync (scan velocity)Dynamic RangeOptical cross-talk anomaly investigation continuesIFA (Integrated Filter Assembly) modifications proposedDecision in NovemberStray light performance accepted for FU1, but trade study for FU2Structural CyroradiatorDecision to add Cold Stage Launch Lock Strain Gauges

  • Sensor Update - CrIS

    FU1 delivery scheduled for May 2008 Frame/Structure Fault to be mitigated by:Reduced test loadsImproved shear panel (Steel vs AlBeMET Aluminum/Beryllium composite) and shoulder boltStrengthened frame design effort continues as a back-upOMA (Optic-Mechanical Assembly) completed all testing; ready for integrationSSM (Scene Selection Module) delivery delayed until late Oct to fix RF connector anomalyPCE (Processing & Control Electronics) delivery now mid-Oct; replacement of shorted backplane connectorsTeam working to define acceptable EMI specification relief (waiver) and risk mitigation

  • Sensor Update - ATMS83GHz and 92GHz Gunn Diode replacement Pre-EDU performance is acceptable57GHz Gunn Diode ReplacementHittite and doubler diode reliability a concern; Alternate designs/additional tests in reviewIF 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

  • Sensor Update - OMPSReceived Limb Profile re-manifest authority to proceedCompleted 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 performanceNadir Diffuser Reflectance DegradationRoot cause outgassing from epoxy tape on Stray Light (SL) bafflesRemove, bake-out and reinstall SL baffles (complete)Clean Nadir Diffusers (complete)Nadir Profiler completed calibration testsThe brass board main Electronics Box (MEB) was integrated to the Limb sensorCompleted risk reduction EMI/EMC testingLimb vibration tests completed successfully

  • ATMS Integrated on NPP SpacecraftNPP ATMS integrated onto NPP Spacecraft

  • CrIS and VIIRS EDU Integrated on NPP Spacecraft

  • Current NPP/NPOESS Program StatusNPOESS Program achieved Nunn-McCurdy recertification in August 2006

    Missions and sensor compliment scaled back

    NPP launch is now Sept 2009; C1 is Jan 2013

    IDPS Build 1.5 completed July 2007

    IDPS hardware installation at NOAA in progress
