NOAA-20/S-NPP VIIRS Environmental Data Record (EDR) Release

Post by kathys »

Dear Colleagues,

The University of Wisconsin-Madison SSEC is pleased to announce the release of a new set of 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) 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.

The CSPP VIIRS ASCI EDR Version 1.0 Software Supports the Following Products:
  • * 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, viirs_asci.sh,
    * Users can choose to create one of 5 product suites, or all products at the same time,
    * Dynamic ancillary data files are automatically downloaded as needed from SSEC servers at runtime,
    * VIIRS EDR algorithms in this release are designed to work with VIIRS SDRs created by CSPP SDR v3.1 and higher. If you are running an earlier version of the CSPP VIIRS SDR algorithm, please upgrade before running the CSPP VIIRS ASCI v1.0 software,
    * 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 6 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. It can be downloaded from the CSPP website:
