CSPP Software: NOAA-20/S-NPP VIIRS Environmental Data Record (EDR) Version 1.1 Release

Dear Colleagues,

The University of Wisconsin-Madison SSEC is pleased to announce a new release of the Community Satellite Processing Package (CSPP) VIIRS Environmental Data Record (EDR) science software in support of the NOAA-20 and S-NPP direct broadcast community.

The JPSS program worked with the CSPP team to integrate the JPSS processing framework enterprise algorithms into stand alone executables, which can then be implemented through simple CSPP bash shell and python scripts. The output files created by this software are identical in naming, format (NetCDF), and structure to the corresponding NPP Data Exploitation system (NDE) files. This CSPP release (VIIRS_ASCI Version 1.1) has been adapted and tested for operation in a real-time direct broadcast environment. A separate test data package can be downloaded for verifying a successful installation.

What is New in CSPP ASCI EDR Version 1.1?

  • VIIRS EDR code base update to 2.3.
    Land Surface Products (Land Surface Temperature, Land Surface Albedo, Land Surface Emissivity).
    Additional quicklooks.
    Target Operating System CentOS7.
The CSPP VIIRS ASCI EDR Version 1.1 Software Supports the Following Products:
  • VIIRS Land Retrievals, including Land Surface Temperature, Land Surface Albedo, and Land Surface Emissivity.
    VIIRS Cloud Retrievals, including Cloud Mask, Cloud Top Properties, Cloud Phase, Cloud Base Height, and Cloud Daytime and Nighttime Microphysical Properties.
    VIIRS Aerosol Retrievals, including Aerosol Optical Depth, and the Aerosol Detection Product.
    VIIRS Cryosphere Retrievals, including Snow Mask, Snow Fraction, Ice Age, Ice Thickness, Ice Concentration, and Ice Surface Temperature.
    VIIRS Volcanic Ash Retrievals, including Ash Confidence, Ash Top Height, Ash Top Temperature, Ash Effective Radius and Ash Optical Depth.
CSPP VIIRS ASCI EDR Software Features:
  • Easy execution through a main bash shell script,,
    Users can choose to create one of 6 product suites, or all products at the same time,
    Dynamic ancillary data files are automatically downloaded as needed from SSEC servers at runtime, or pre-loaded through a separate ancillary script,
    Multi-core processing is supported (-p option).
CSPP VIIRS ASCI EDR System Requirements
  • Intel or AMD CPU with 64-bit instruction support,
    4 GB RAM (minimum) per core,
    CentOS 7 64-bit Linux (or other compatible 64-bit Linux distribution),
    50 GB disk space (minimum),
    Internet connection (for downloading dynamic ancillary data).
Scott Mindock leads the CSPP VIIRS ASCI EDR development at the Space Science and Engineering Center located at the University of Wisconsin-Madison with funding support from the NOAA/NASA Joint Polar Satellite System (JPSS). The CSPP VIIRS ASCI software package contains binary executable files, driver scripts, static ancillary data files, detailed documentation, and test data for verification of a successful installation.
