  Suomi National Polar-orbiting Partnership (S-NPP) and NOAA-20 Sensor Data Record (SDR) Software Version 3.1 Release with Patches 3.1.1 and 3.1.2

29 January 2019

     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 Suomi-NPP and NOAA-20 Satellites.

This version includes a Patch that corrects bugs to improve the granule yields for all instruments from RDR inputs (Version 3.1.1) and a Patch to fix a problem with incomplete download of S-NPP and NOAA-20 VIIRS SDR Look-Up-Tables (LUTs). The Patches can either be included as part of a new installation, or applied to an existing CSPP Version 3.1 installation. Follow the instructions in the CSPP SDR Version 3.1.2 Installation Guide.

Please note: The CSPP SDR Version 3.1.2 Patch is not inclusive; users need to install the Version 3.1.1 Patch followed by the Version 3.1.2 Patch separately. Instructions for installing Version 3.1.1 Patch followed by the Version 3.1.2 Patch can be found in the CSPP Version 3.1.2 Installation Guide.

What is new in CSPP SDR Version 3.1.2:

  • Fixed bug that limited the number of S-NPP and NOAA-20 VIIRS Look-Up-Tables (LUTs) that can be downloaded.

What is new in CSPP SDR Version 3.1.1:

  • Fixed two bugs in CSPP SDR v3.1 which resulted in reduced SDR granule yields for each instrument.

What is new in CSPP SDR Version 3.1:

  • The code base is updated to Block 2.1 Mx2 (ADL5.3_I2.1.02).
  • Filtering is now performed by default to remove incomplete or partial ATMS and CrIS RDR granules prior to processing. This behavior can be controlled using option -s.
  • Improved Look-Up-Table (LUT) and ancillary data download and storage.
  • Fixed bug that repeated storage of LUT and ancillary data sets into the database.
  • New ancillary and LUT distribution site is used: http://jpssdb.ssec.wisc.edu/cspp_v_3_1/ .

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

System requirements for CSPP SDR Version 3.1 have not changed from the Version 3.0 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),
  • Internet connection (for downloading ancillary 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 NOAA-20 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/NOAA-20 file formats are available here (see the Common Data Format Control Books).

Software, documentation and test data for this CSPP SDR Version 3.1 release are available for download following the link below.
