Polar Constellation Special Session S-NPP Status

1. Polar Constellation Special Session S-NPP Status by: Dr. Martin England NESDIS/OSPO S-NPP Engineering Team Lead

2. S-NPP Mission Objectives • EOS data continuity is maintained; that S-NPP provides research quality data products which can be used in a single stream from EOS Terra, Aqua or Aura to analyze and determine actual geophysical trends in climate parameters; • S-NPP flight and ground systems performance leads to validation and/or improvements in JPSS designs and procedures for future missions; • S-NPP data are able to support the NOAA weather forecasting and ocean missions.

3. S-NPP Mission Architecture

4. Mission Systems Status S-NPP Space System is GREEN Operational (or capable of) Operational with limitations (or standby) Operational with degraded performance Not functional

5. Mission Operations and Overall Mission is GREEN • Mission Operations (S-NPP) running smoothly • 99.99% Ad (spec 99.90%) and 99.53% Ld (spec 95.00%) avg 79.2 mins • ATO received July 2013

6. Maneuvers affecting data quality

7. How are we doing in meeting our Objectives? Comparisons of Monthly Mean of VIIRS Deep Blue AOD with VIIRS IDPS for July 2012 VIIRS DB retrieves aerosols over desert and semi-desert regions, which are entirely missing in VIIRS IDPS AOT products Suomi NPP can be used to produce EOS Products not produced by IDPS Objective: • EOS data continuity is maintained; that S-NPP provides research quality data products which can be used in a single stream from EOS Terra, Aqua or Aura to analyze and determine actual geophysical trends in climate parameters;

8. How are we doing in meeting our Objectives? Objective: • S-NPP flight and ground systems performance leads to validation and/or improvements in JPSS designs and procedures for future missions; Block 2 Improvements Multi-satellite capability Multiple independent strings Nominal backup facility (CBU) in WV JPSS-1 Improvements CrIS default mode will be “Full Spectrum” for all channels Replace Firewire with Space Link VIIRS hardware Watchdog timer

9. How are we doing in meeting our Objectives? Objective: • S-NPP data are able to support the NOAA’s weather forecasting and ocean missions. Cross-track Infrared Sounder Operational Users • May 1, 2012, VIIRS imagery used to support local warning and forecast operations throughout the NWS Alaska Region. • May 22, 2012, the Advanced Technology Microwave Sounder (ATMS) radiances were operationally assimilated in the National Centers for Environmental Prediction’s (NCEP)/ NWS Global Forecast System (GFS). • September 25, 2012, ATMS data was assimilated operationally into the European Centre for Medium-Range Weather Forecasts (ECMWF) weather forecast models. • April 2013, the United Kingdom Meteorology Office began assimilating operational data from the Cross-track Imaging Radiometer Suite (CrIS) and ATMS into its weather forecast models. • August 20, 2013, NCEP began incorporating S-NPP CrIS satellite data operationally into the GFS. • October 31, 2013, NCEP/CPC started to use OMPS Ozone operationally • November, 2013, NRL started to use ATMS operationally in their global forecast model.
