4. Archived SNPP Data • NOAA’s archive system: Comprehensive Large Array-data Stewardship System (CLASS, http://www.class.noaa.gov/) • Data delayed by 6 hours or more - normally available to users within 24 hours. • NOAA archives: • Raw, sensor and environmental data records (RDRs, SDRs, EDRs) • Ancillary and auxiliary data • Software release packages • Registered calibration and validation team members have immediate access to new data sets. • Registered public users have access after JPSS Program Office declares products have reached β and/or Provisional status. NOAA Satellite and Information Service: National Environmental Satellite, Data, and Information Service (NESDIS)

5. SNPP Data Exploitation (NDE) Project Overview • NDE MISSION: • The NDE Project’s primary mission is to provide near real time products derived from SNPP observations to NOAA’s operational and climate communities and other civilian and U.S. Government users.

7. Near Real Time SNPP Data • NOAA’s NPP Data Exploitation (NDE) Project • NDE’s scope is to serves the near real time user community • Currently distributing data to priority users on best-effort basis • Product access capabilities include SNPP SDRs, EDRs and NDE Unique Products (NUPs) with tailoring options • NOAA’s Office of Satellite and Product Operations (OSPO) provides a 24x7 Help Desk facility to report data anomalies • FTPS protocol per RFC 4217 (encrypted control, unencrypted data), push and pull • NOAA will not monitor production on a 24x7 basis until late summer 2013 following NDE system handover to NESDIS operations • NOAA is preparing a SNPP Ground System remote backup capability in 2015 NOAA Satellite and Information Service: National Environmental Satellite, Data, and Information Service (NESDIS)

8. Near Real Time SNPP Data(cont.) • NOAA’s NPP Data Exploitation (NDE) Project (cont.) • Users must: • Submit SNPP Data Access Request (DAR) Form to NESDIS.Data.Access@noaa.gov • Requests involving large data volumes will require the user to establish a communication capability to access SNPP data. Limited tests may be conducted via Internet • SNPP DAR Approval/Evaluation Process is being executed • Led by OSPO’s Data Operations Manager • Supported by NDE and OSPO Representatives • Direct Readout Capability (X-Band) can be used to receive SNPP data in regional areas • The Community Satellite Processing Package-Direct Readout Science Processing Algorithm (CSPP-DR_SPA) NOAA Satellite and Information Service: National Environmental Satellite, Data, and Information Service (NESDIS)

9. Near Real Time SNPP Data(cont.) • Global Telecommunications Service (GTS) & European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) • EUMETSAT redistributes/makes available the NDE delivered CrIS and ATMS radiance sensor data records in BUFR format on GTS and EUMETCast (Activated on 31 July 2012) • GTS is used for operational international exchange of meteorological data between National Centers • EUMETCast is a satellite multicast system using DVB-S technology. Users register for access via EUMETSAT NOAA Satellite and Information Service: National Environmental Satellite, Data, and Information Service (NESDIS)

10. Sample SNPP Data Sets • NOAA’s research office has placed sample data sets at the following locations: • BUFR ATMS and CrIS 399 channel files: • ftp://ftp2.orbit.nesdis.noaa.gov/smcd/tking/ATMS_BUFR/ • ftp://ftp2.orbit.nesdis.noaa.gov/smcd/tking/CrIS_BUFR/ • NOAA Unique CrIS-ATMS Product System (NUCAPS) EDR files: • ftp://ftp2.star.nesdis.noaa.gov/smcd/tking/NUCAPS/EDR/ • VIIRS BUFR files: • ftp://ftp2.star.nesdis.noaa.gov/smcd/ysong/VIIRS/Iband-SDR/ • Sea Surface Temperature (SST) BUFR files: • ftp://ftp2.star.nesdis.noaa.gov/smcd/ysong/SST/ • Advanced Clear-Sky Processor for Oceans (ACSPO) SST files: • ftp://www.star.nesdis.noaa.gov/pub/sod/osb/jstroup/ACSPO/sampleData/viirs/EUMETSAT/ NOAA Satellite and Information Service: National Environmental Satellite, Data, and Information Service (NESDIS)
