Suomi National Polar-orbiting Partnership (S-NPP) and NOAA-20 Sensor Data Record (SDR) Software Version 3.2.1
16 March 2021The CSPP Team is releasing a Patch to the SDR Version 3.2 software (v3.2.1) that includes an improvement in the handling of corrupt VIIRS RDR science data. This code update was provided by the VIIRS SDR Algorithm team. This improvement also has a positive impact on downstream Environmental Data Record (EDR) product retrievals too, including the VIIRS Active Fires. The Patch also includes a change in filtering input RDR ATMS and CrIS instrument inputs that can improve the output SDR geolocation accuracy. Follow the instructions in the CSPP SDR Version 3.2.1 Installation Guide to apply the Patch to a new or existing CSPP SDR Version 3.2 installation. The CSPP Sensor Data Record (SDR) software 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 JPSS Suomi-NPP and NOAA-20 Satellites for Direct Broadcast users.

What is new in CSPP SDR Version 3.2:
The CSPP SDR version 3.2 software continues to support a number of unique features:
System requirements for CSPP SDR Version 3.2:
Other things to note:
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 and NOAA020 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).
