This is the coupled WRF-Fire model, combining WRF and the SFIRE codes.

If you find this code useful please acknowledge our work by citing the paper
[1].  Yes this is a strange reference for an atmospheric scientist but it  
is the only one we have at the moment. Please see the sections
"Fireline propagation model", "Coupling fire and weather models", and
"Level-set-based wildland fire model".  The fire model is based on [2] 
but not all features from [2] are implemented here yet.

We hope you find the code useful. Please let us know if we can help. But
do us a favor and before you ask a question (such as, what is git?) 
please google first. You may need to find a local guru for Linux questions.
Thank you!

Answers to any questions may be copied or summarized to the wrf-fire list.


COMPILERS

Tested on linux/ifort/gcc, linux/pgi, linux/g95 (all x86-64), and mac/g95. 
Mac will not run optimized or real data, though. ifort for Linux can be 
downloaded from Intel free for non-commercial use. gfortran is not included 
because gfortran currently cannot compile wrf.


SETUP 

We strongly recommend using git not a tar file to download the code
so that you can get updates easily and also keep your changes. 
You will probably need to install git.  A current version (now 1.6) 
recommended. You may need to install git from sources.

Download NETCDF and install. The curent version is 4.0 Some hints: 
Set the environment variables CC FC and F90 to your compilers. 
Set the install location by something like 
./configure --prefix=/opt/netcdf 
(Of course, use your own location)
Set the environment variable to the top level netcdf directory like:
setenv NETCDF /opt/netcdf
(Of course, replace the path by your location of NETCDF above)

Local developers can source env.csh with setup for some local machines where
NETCDF is already installed.


HOW TO GET THIS CODE

The code can be downloaded from http://github.com/jbeezley/wrf-fire/ by

 	 git clone git://github.com/jbeezley/wrf-fire.git


Local developers get the code and submit changes by 

         git clone ssh://math.cudenver.edu/home/grads/jbeezley/wrf-fire.git


BRANCHES

Use the code from the master branch as it is the only stable one. Use other
branches only if instructed by the developers. We recommend to set up your own
branch for your changes and merge master into it when it is updated.
See doc/README_git.txt


BUILDING

 
cd wrfv2_fire
./configure # select an option for your computer architecture/compilers
	    # If you are trying to get this working on different
	    # compilers, try copying a section close to your case
            # in arch/configure_new.defaults to the end of that file
            # and modifying to suit your needs... good luck.
./compile em_fire >& compile.log

This will take a while.  Make sure that compile.log contains 
no errors.  ("grep Error compile.log" shouldn't return anything).


RUNNING

cd test/em_fire/small 
./ideal.exe >& ideal.log (this creates file wrfinput_d01, needs to be done only
when input_sounding changes)
./wrf.exe

This runs an "idealized" problem. 
For RUNNING ON REAL DATA see doc/README_wps.txt


STANDALONE FIRE MODEL TEST

With ifort:

cd phys
./ifmake clean
./ifmake model_test

Without the clean between different kind of builds nothing will work.
There is g95make for g95.
With other compilers, try someting like 

    make -f testmakefile FC=your fortran compiler

See wrfv2_fire/phys/README_jm.txt for more info.

NOTE: maintaining the standalone model is low priority and it may not work.
