Community Satellite Processing Package

  Suomi National Polar-orbiting Partnership (S-NPP) and JPSS-1 Sensor Data Record (SDR) Software Version 3.0 Release

12 October 2017

     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 onboard the JPSS S-NPP and JPSS-1 Satellites.

What is new in CSPP SDR Version 3.0:

  • CSPP SDR v3.0 is ready to process VIIRS, ATMS, and CrIS data from JPSS-1.
  • CSPP SDR code base has been updated to Block 2.0 ADL Version 5.3.16 (Mx3).
  • CrIS Normal Spectral Resolution (NSR) and Full Spectral Resolution (FSR) SDR processing is supported.
  • CrIS and ATMS output yield for direct broadcast processing has improved (more granules are created for each pass) due to improved handling of incomplete granules.
  • CrIS NSR processing times are shorter, due to Correction Matrix Operator (CMO) data being included with the software package as a lookup table instead of being computed at runtime.
  • New dynamic ancillary and Look-Up-Table (LUT) update scripts have been created for compatibility with the database used internally by Block 2.0 ADL. These scripts are the recommended way of acquiring dynamic support data for CSPP SDR processing.
  • A single script (ql_sdr.sh) is now used to create VIIRS, CrIS and ATMS quicklook images.

This release replaces existing installations of CSPP SDR (it is not an update).

System requirements for CSPP SDR Version 3.0 have not changed from the Version 2.x releases:

  • Intel or AMD CPU with 64-bit instruction support,
  • 16 GB RAM, plus an additional 8GB of RAM for every core that is used for CSPP VIIRS SDR processing,
  • CentOS 6 64-bit Linux (or other compatible 64-bit Linux distribution,
  • 100 GB disk space (including the software and data).

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 and JPSS-1 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 the SDR products is HDF5, and descriptions of the S-NPP/JPSS-1 file formats are available here (see the Common Data Format Control Books).

Software, documentation and test data for this CSPP SDR Version 3.0 release are available for download following the link below.
