  Suomi National Polar-orbiting Partnership (NPP) VIIRS Environmental Data Records (EDR) Software Version 2.0 Release

4 August 2014

CSPP software package for transforming direct broadcast Suomi-NPP Visible Infrared Imaging Radiometer Suite (VIIRS) Sensor Data Records (SDRs) into Environmental Data Record (EDR) products on Intel Linux computers. Supported EDR products include,
  • VIIRS Cloud Mask (IIMCO*.h5),
  • VIIRS Active Fires (AVAFO*.h5),
  • VIIRS Aerosol Optical Thickness (VAOOO*.h5),
  • VIIRS Suspended Matter (VSUMO*.h5) and
  • VIIRS Sea Surface Temperatures (VSSTO*.h5),
  • VIIRS Surface Reflectance (IVISR*.h5),
  • VIIRS Normalized Difference Vegetation Index (VIVIO*.h5), and
  • VIIRS Enhanced Vegetation Index (VIVIO*.h5).
with these new products,
  • VIIRS Surface Type (VSTYO*.h5), and
  • VIIRS Land Surface Temperatures (VLSTO*.h5).
What else is new in CSPP VIIRS EDR 2.0?
  • The EDR software matches NOAA Operational IDPS version Mx8.4 (ADL 4.2.4),
  • A new CSPP ancillary data distribution website for version 2.0 algorithms is now required

The CSPP VIIRS EDR algorithms are designed to work with CSPP VIIRS SDR version 2.0. They are *not* designed to work with earlier versions of the VIIRS SDR products (e.g., CSPP VIIRS SDR v1.5).

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).
