35 #This command will run a series of python scripts that grab data specific
36 #to your domain and convert it to geogrid format. If everything goes well,
37 #it will run geogrid.exe with the new data.
38 #!!! REQUIRES a number of external utilities:
39 #!!! Python 2.5+ (www.python.org)
40 #!!! GDAL library and python bindings (www.gdal.org)
41 #!!! (See the binary distributions in the downloads section.)
42 #!!! twill (http://twill.idyll.org)
43 #!!! (Install with python's easy_install or simply extract the source somewhere
44 #!!! and add that path to PYTHONPATH.)
46 #If you can't satisfy these dependencies, you must generate fuel category and
47 #highres topological data on your own. The datasets are simply too big to distribute
48 #in one package like the rest of geogrid.

73 #To set up a new case for a real data fire simulation, the procedure is similar
74 #to the standard documentation for WPS. First you must edit the namelist.wps
75 #for the domain you wish to simulate. (The namelist variables sr_x/sr_y
76 #describe the subgrid scaling as in wrffire.) Then you must download
77 #atmospheric boundary conditions for the day you want, for instance from here:
78 #http://dss.ucar.edu/datasets/ds083.2/data/
80 #This data and variable table must be linked into the WPS directory as above.
81 #If you use ucar/ncep data the variable table is Vtable.AWIP.
83 #Finally, run the wps programs geogrid, ungrib, and metgrid. Then go to the
84 #wrf real test directory, link in the metgrid output, and set up the namelist
85 #for the new domain. (If the domain description differs from the wps namelist,
86 #real.exe will not run successfully.) Run real.exe and wrf.exe.
