Suomi National Polar-orbiting Partnership (S-NPP), NOAA-20 and NOAA-21 Sensor Data Record (SDR) Software Version 4.0
27 April 2023
A new CSPP SDR software release supporting the calibration and geolocation of the Visible Infrared Imaging Radiometer Suite (VIIRS), Advanced Technology Microwave Sounder (ATMS), Cross-track Infrared Sounder (CrIS) and the Ozone Mapping and Profiler Suite (OMPS) Nadir Mapper (NP) and Nadir Profiler (NP) instruments onboard the JPSS Suomi-NPP, NOAA-20 and NOAA-21 satellites from input Raw Data Records (RDRs). The software is designed to support RDRs acquired via direct broadcast but can also ingest NOAA CLASS archived files as well.

The CSPP SDR Version 4.0 Software Supports Unique Features:
System requirements for CSPP SDR Version 4.0:
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, NOAA-20 and NOAA-21 to run without modification in a Linux environment. SSEC has packaged the ADL versions of the 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/NOAA-21 file formats are available here (see the JPSS Common Data Format Control Book).
