NPOESS Data ExploitationNPOESS 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

Examples ofExamples ofNPP/NPOESS NOAA Unique ProductsNPP/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

NOAA Satellite Operations FacilityNOAA Satellite Operations Facility(NSOF)(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)

NPOESS Preparatory Project: IPO-NASA Risk NPOESS Preparatory Project: IPO-NASA Risk Reduction DemoReduction 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

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

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

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

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
