CSPP SDR v3.0 for SNPP and JPSS-1

Post by kathys »

Dear Colleagues,

The Community Satellite Processing Package (CSPP) project at CIMSS/SSEC/UW-Madison is pleased to announce the public release of the CSPP Sensor Data Record (SDR) version 3.0 software for Suomi NPP and JPSS-1. This software package supports 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 Suomi NPP and JPSS-1 satellites.

What’s new in CSPP SDR version 3.0:
  • • Ready to process VIIRS, ATMS, and CrIS data from JPSS-1.
    • 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.
Note that this release replaces existing installations of CSPP SDR (it is not an update).

The CSPP SDR version 3.0 software continues to support a number of unique features:
  • • Optional multi-core processing to reduce wait times while the SDR data are created (supported for VIIRS, CrIS, and ATMS),
    • Optional aggregation and compression of SDR output files,
    • Automated download of required ancillary data at runtime, plus offline scripted downloads,
    • Offline scripted downloads of calibration lookup tables (LUTS).
System requirements for CSPP SDR version 3.0 have not changed from the CSPP SDR version 2.2 release:
  • • 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 (for the software and accompanying data).
The CSPP SDR version 3.0 software 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 and JPSS-1 to run without modification in a Linux environment. CIMSS/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 SDR file format and contents are available in CDFCB Volume III at:

The CSPP SDR version 3.0 software, documentation and test data is now available for download at
