  Suomi National Polar-orbiting Partnership (NPP) Sensor Data Record (SDR) Software Version 2.2 Release

1 April 2016

     New SDR package 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 onboard the JPSS S-NPP satellite.

What is new in CSPP SDR Version 2.2:

  • Updated code base to ADL 4.2.11 (Mx8.11).
  • Updated ancillary data scripts.
  • Added new VIIRS ancillary data set dependence - a daily reflective solar calibration coefficients file.
  • VIIRS M-Band 6 SDR radiance to reflectance changes.
  • Quick look display and execution performance improvements including CrIS image interpolation through deleted direct broadcast FOVs.
  • CSPP SDR Version 2.2 can be used for creating VIIRS, CrIS and ATMS SDRs from historical data sets beginning on 5 July 2014 to the present.

Much more information is available in the Installation Guide that is distributed with the software. This release replaces existing installations of CSPP SDR (it is not an update). Please note that the CACHE and STATIC tarballs from CSPP V2.1 cannot be reused with this 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).
