Fire module in WRF 3.3

This page tracks the evolution of the fire module from the submission to the 3.3 release.

Release branch

To track the files. branch WRF_release_3.3 was created starting from the files as submitted, applied one submitted bug fix, and ending the with files from the WRF 3.3 release at http://www.mmm.ucar.edu/wrf/src/WRFV3.3.TAR.gz

Links to versions

• Version Nov 20, 2010 as originally submitted to WRF committee for the 3.3 release
• Bug fix Jan 18, 2011. This is the final version submitted to the WRF committee.
• Files after changes at NCAR in the submitted fire module files. These changes consist of
  • Janice's changes in fire module files. See also her post describing the additional changes.
    • Various small edits to comments all over.
    • Deleted essentially all attributions [1] [2] [3] [4] [5]
    • Small (max about 1%) changes to default values of fuel data variables [6]
    • Deleted the use of fuel variable windrf [7] [8]. This has the same effect as setting all windrf=1 in the data with the submitted code. The default value of fire_wind_height was not changed in the registry and remains at 6.096m; this results in 2-3 times increase of wind-driven spread rates when running the code at defaults. The intention was to set fire_wind_height to a smaller value in the namelist, but then the value is the same for all fuels. Wind interpolation to different heights for different fuels came later and it is not in the release.
    • Renamed ros_back to ros_base [9], added local variable ros_back [10] used only in chapparal. Two lines change results: [11] in the MacArthur formula and [12] in chaparral both have the effect of increasing the spread rate by adding the zero-wind rate.
    • Deleted the identification of the git commit the files come from [13] [14]
    • Replacing all examples by two new ones.
  • Routine software engineering changes: Added ONLY to USE statements [15] [16] [17] [18] [19] [20]
• Final files in the release after changes to the rest of the files
