  CSPP NOAA JPSS VIIRS Active Fire Software Version 1.0 Release

31 October 2017

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) Active Fire 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.

Some facts about the new CSPP NOAA VIIRS Active Fire Software:

  • It is the NOAA operational version ported for application to direct broadcast inputs;
  • It replaces the active fire software that is distributed as part of the CSPP EDR software suite;
  • It currently produces output at M-Band resolution, but will be updated in the near future to work with I-Band inputs.
Two output products types are produced per granule at M-Band spatial resolution.

1) NetCDF4 product file containing 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;
  • Band 13 brightness temperature of fire pixel (K);
  • Band 15 brightness temperature of fire pixel (K);
  • Fire radiative power (MW).

2) 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).

Please note that the ASCII Text File is created for a VIIRS granule when there has been at least one active fire detected within that granule. Therefore, your output may consist of more NetCDF4 granule data files than ASCII output granule text files.

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).

The software, test data and installation guide are available at the CSPP Download site.
