  Suomi National Polar-orbiting Partnership (NPP) Science Data Record (SDR) Software Version 1.3 Release

8 February 2013

     New SDR packages supporting the calibration and geolocation of the Visible Infrared Imaging Radiometer Suite (VIIRS), Advanced Technology Microwave Sounder (ATMS), and the Cross-track Infrared Sounder (CrIS) instruments. This version is designed to work with the initial release of the VIIRS Active Fires and Cloud Mask CSPP Environmental Data Records software.

What is new in CSPP SDR Version 1.3:

  • SDR software now matches the version running in NOAA IDPS operations (Mx6.5),
  • VIIRS SDR now uses predictive solar calibration,
  • ew directory structure starting with SDR_1_3 as the top level,
  • Internal ADL version updated to ADL v4.1,
  • New ancillary data logic allows disabling of ancillary data downloads at runtime,
  • VIIRS SDR is compatible with the CSPP VIIRS EDR v1.0 software release.

The CSPP SDR software package is based on the Algorithm Development Library (ADL) software developed by Raytheon for the JPSS Project. ADL allows the operational processing algorithms for Suomi NPP to run without modification in a Linux environment. SSEC has packaged the ADL versions of the Suomi NPP algorithms so they can run from the Linux command line in real-time direct broadcast mode, but we have not changed the underlying processing software, algorithms, or data formats. The output files from the CSPP SDR processing software are identical in naming, format, and structure to the corresponding files from NOAA/NESDIS. The native format for NPP SDR products is HDF5, and descriptions of the NPP file formats are available here (see the Common Data Format Control Books).
