  Suomi National Polar-orbiting Partnership (NPP) Science Data Record (SDR) Software Version 1.1 Release

2 May 2012

     First CSPP NPP Release supporting the Cross-track Infrared Sounder (CrIS) instrument. The version 1.1 software also includes updates to the Visible Infrared Imaging Radiometer Suite (VIIRS) and Advanced Technology Microwave Sounder (ATMS) instruments software packages. The software uses input Raw Data Records (RDRs) from Direct Broadcast and transforms them into calibrated and geolocated Science Data Records (SDRs) in JPSS Common Data Format Control Book (CDFCB) HDF5 format.

Along with the release of the CrIS SDR package, updates to the software have been made in response to user requests, including:

  • All packages have improved runtime logging information.
  • All packages have improved work directory file cleanup upon completion.
  • VIIRS Look Up Tables (LUTs) have been updated.

The CSPP software for Suomi NPP is based on the Algorithm Development Library (ADL) developed by Raytheon and the JPSS project. This means that the CSPP software is the same software that runs in the operational processing facility at NOAA/NESDIS. SSEC has packaged the software to 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).
