'''WRF-Fire''' combines the Weather Research and Forecasting model ([[WRF]]) with a surface fire behavior model. Semi-empirical formulas calculate the rate of spread of the fire line, the interface between burning and unignited fuel, based on fuel properties, wind velocities from WRF, and terrain slope. This interface is implemented by the [[wikipedia:Level set method|level set method]]. The heat release from the fire line as well as post-frontal heat release feeds back into WRF dynamics, affecting the simulated weather in the vicinity of the fire. WRF-Fire is written in [[wikipedia:Fortran|Fortran 90]] following [http://www.mmm.ucar.edu/wrf/WG2/WRF_conventions.html WRF coding conventions]. It is integrated as a physics option, called from WRF as a subroutine. It calls WRF libraries for utilities such as I/O and communication between [[MPI]] processes. WRF-Fire executes on a part of the domain, called a tile (in WRF nomenclature). All communication between the tiles is in the caller; thus, one time step requires multiple calls to WRF-Fire. WRF-Fire can also be run independently without an atmosphere model by substituting its own main program and linking with stubs that replace the WRF subroutines called, although this capability has fallen behind at the moment and is not physically meaningful.

==Contributors==

* Janice Coen (NCAR) developed the physics components of the fire model in [[CAWFE]] (Coen (2005) and Clark et al. (2004)), in particular the fire spread rate and the heat flux insertion modules, which were adopted into WRF-Fire with no substantial changes.
* Ned Patton (NCAR) ported the fire code from (Clark et al., 2004) and interfaced it with WRF (Patton and Coen, 2004).
* Minjeong Kim and Jan Mandel (University of Colorado Denver) have identified a version of the level set metod suitable for fire spread, and developed a prototype Matlab code.
* Jan Mandel (University of Colorado Denver)has implemented the fire spread by the level set method as a parallel WRF-compliant code with assistance from Jonathan Beezley and Minjeong Kim, starting from Ned Patton's WRF interface and using the subroutines for the spread rate computation and the insertion of heat fluxes into the atmosphere from CAWFE.
* John Michalakes (formerly NCAR, now NREL) modified WRF to support refined grids (submesh) for the fire code.
* Jonathan Beezley (University of Colorado Denver) has further modified WRF to support the fire software, provided the software engineering infrastructure, has set up and maintains the git repository, maintains synchronization with WRF changes, and developed the modified version of WPS for WRF with the fire model to enable the use of real data.
* Volodymyr Kondratenko (University of Colorado Denver) has improved memory handing in the computation of remaining fuel.
* Adam Kochanski (University of Utah) has contributed variable atmospheric bubble initialization and suggested the walking line ignition. He is currently leading the validation effort.
* Kara Yedinak (Washington State University) has improved in fire initialization. See [[Talk:WRF-Fire development notes#Gradual ignition|discussion]]

* Janice Coen developed the physical fire model, which is the same as in [[CAWFE]] (Coen (2005) and Clark et al. (2004))
* Ned Patton (Patton and Coen, 2004), ported the earlier fire code from (Clark et al., 2004) and interfaced it with WRF.

{{software}}
'''WRF-Fire''' combines the Weather Research and Forecasting model ([[WRF]]) with a surface fire behavior model. Semi-empirical formulas calculate the rate of spread of the fire line, the interface between burning and unignited fuel, based on fuel properties, wind velocities from WRF, and terrain slope. This interface is implemented by the [[wikipedia:Level set method|level set method]]. The heat release from the fire line as well as post-frontal heat release feeds back into WRF dynamics, affecting the simulated weather in the vicinity of the fire. WRF-Fire is written in [[wikipedia:Fortran|Fortran 90]] following [http://www.mmm.ucar.edu/wrf/WG2/WRF_conventions.html WRF coding conventions]. It is integrated as a physics option, called from WRF as a subroutine. It calls WRF libraries for utilities such as I/O and communication between [[MPI]] processes. WRF-Fire executes on a part of the domain, called a tile (in WRF nomenclature). All communication between the tiles is in the caller; thus, one time step requires multiple calls to WRF-Fire. WRF-Fire can also be run independently without an atmosphere model by substituting its own main program and linking with stubs that replace the WRF subroutines called, although this capability has fallen behind at the moment and is not physically meaningful.

==Distribution==

WRF-Fire is public domain software, [http://github.com/jbeezley/wrf-fire/blob/master/license.txt released] under the [http://www.mmm.ucar.edu/wrf/users/public.html WRF public domain notice and disclaimer].

===Current development version===

This version also contains a number of additional tools such as [[Matlab]] scripts for visualization. See [[How to get WRF-Fire]] and [[How to run WRF-Fire]] for installation instructions.

==Contact==

==File format==

All input, output, and restart files (with the complete model state) are in [[NetCDF]] format.

==Programming language and environments==

Fortran 90 with CPP preprocessor. Part of the WRF code is generated by C programs from a description in the registry.

==Documentation==

===Technical description===

* [[Media:Wrf-fire-doc.pdf|Description of the fire scheme in WRF]] describes the algorithms and software structure of WRF-Fire. It is intended to become a chapter in the [http://www.mmm.ucar.edu/wrf/users/docs/arw_v3.pdf WRF Technical Note] in future. The description is based on sections ''Fireline propagation model'' and ''Level set-based wildland file model'' in Jan Mandel, Jonathan D. Beezley, Janice L. Coen, Minjeong Kim, ''Data Assimilation for Wildland Fires: Ensemble Kalman filters in coupled atmosphere-surface models'', [http://dx.doi.org/10.1109/MCS.2009.932224 IEEE Control Systems Magazine 29, Issue 3, June 2009, 47-65]. Preprint at [http://arxiv.org/abs/0712.3965 arXiv:0712.3965], December 2007. This is currently the only journal publication about WRF-Fire.

==Support==

===Email support===

Questions regarding WRF-Fire can be sent to [mailto:wrffirehelp@openwfm.org wrffirehelp@openwfm.org]. This email address is forwarded to the developers. When you write us, please:

* Identify the version (WRF version if from the WRF release, the first line of the output of <code>git log</code> if your code is from the git repository)
* Make sure you test the issue first on the code exactly as you have received it and the code version is up to date. If you obtained the code by [[git]] ''(highly recommended)'' as described in [[How to get WRF-Fire]],
** <code>git diff</code> should return no output
** please verify that you are on the latest commit on the master branch from the repository.
* Recompile the code from scratch after typing <code>clean -a</code> first
* Send us sufficient information to identify and reproduce the problem if needed (output of wrf compilation, namelist.input, output from the run)

===Mailing list===
