   6 #!!! This data case only starts a fire somewhere in the mountains

  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

  71 # SET UP A NEW CASE
  72 #
  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/
  79 #
  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.
  82 #
  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.
  87 #
