! SFIRE - Spread fire model in WRF-Fire
!
!*** Jan Mandel August 2007 - July 2010
!*** email: Jan.Mandel@gmail.com
! For support please subscribe to the wrf-fire mailing list at NCAR at
! http://mailman.ucar.edu/mailman/listinfo/wrf-fire
! or go to http://www.openwfm.org/wiki/WRF-Fire_user_support
! This module is the only entry point from WRF-ARW to the wildland
! fire model. The call to sfire_driver advances the fire model by
! one timestep. The fire model inputs the wind and outputs
! temperature and humidity tendencies. The fire model also inputs a
! number of constant arrays (fuel data, topography). Additional
! arguments are model state (for data assimilation) and constant arrays
! the model gives to WRF for safekeeping because it is not allowed
! to save anything.
! This code is described in [1,5]. The fire model is coupled with WRF
! but the fire code itself is not dependent on WRF in any way other
! than calls to few WRF utilities from module_fr_sfire_util. This
! model uses a level set function method for advancing the fireline.
! It is a reimplementation of an earlier model, which used fireline
! propagation by tracers and was coupled with the Clark-Hall
! atmospheric code, described in [2]. For WRF documentation see [3].
! If you use this code, please acknowledge our work by citing [1].
! Thank you.

! method by Mijeong Kim. Contribution to fuel calculation by Volodymyr

! The fire physics is adapted from an earlier code by Terry
! L. Clark, Janice L. Coen, and Don Latham [2]. The interface with
! WRF is adapted from a code by Ned Patton for coupling of the earlier
! fire model with WRF, based on the foundation outlined in [4].
! The changes in WRF infrastructure and support of
! refined fire grids were provided by John Michalakes.
! Jonathan D. Beezley has set up and maintained the WRF build and
! execution environment, provided software engineering infrastructure
! including synchronization with the WRF repository, and was responsibe
! for all aspects of WRF modification.
