The Community Satellite Processing Package (CSPP) project at CIMSS/SSEC/UW-Madison is pleased to announce the release of the NOAA JPSS operational VIIRS Active Fire Software in support of direct broadcast Suomi-NPP.
The NOAA JPSS Active Fires Team is led by Ivan Csiszar at the NOAA NESDIS Center for Satellite Applications and Research (STAR). This CSPP release provides the NOAA STAR S-NPP Data Exploration (NDE) operational version adapted and tested for execution in a real-time direct broadcast environment. The software contains binary executable files, wrapper scripts and supporting static data files. A separate test data package can be downloaded for verifying a successful installation.
This software is an upgrade and replacement for the CSPP Active Fire software that is part of the CSPP Environmental Data Record (EDR) product software suite.
The software currently uses S-NPP VIIRS M-Band resolution Sensor Data Record (SDR) inputs, but will be updated in the near-future to work with I-Band inputs.
Two output product files are produced for each granule at M-Band pixel resolution. These product types are:
1) A NetCDF4 product file that includes these Key Parameters:
- a fire mask that includes the confidence of fire at that pixel (%)
- location of the active fire in terms of granule line/element and latitude/longitude.
- M-Band 13 brightness temperature of fire pixel (K)
- M-Band 15 brightness temperature of fire pixel (K)
- Fire radiative power (MW)
2) An ASCII Text File containing the following information:
- Latitude of fire pixel (degrees)
- Longitude of fire pixel (degrees)
- M-Band 13 brightness temperature of fire pixel (K)
- Along-scan fire pixel resolution (km)
- Along-track fire pixel resolution (km)
- Fire detection confidence (%)
- Fire radiative power (MW)
In addition to describing how to install and execute the software, the installation guide includes instructions on overlaying the output fire product onto an underlying GeoTIFF image (either Polar2Grid true color or a Blue Marble background).
