HFire was developed by Marco Morais when he was a graduate student in the Department of Geography at the University of California, Santa Barbara (read his thesis here). In addition to working at the Southern California Wildfire Hazard Center, Mr. Morais completed his M.A. in Physical Geography with an emphasis in Modeling, Measurement and Computation. The HFire model has been released under the GNU Lesser General Public License, complete source code and compiled executables are available for download.
