Readme file for STILT/WRF interface tar ball, for version v3.2 and
later of the WRF model.

1. Codes assembled here are to enable use of the WRF-STILT interface as
  described in 

  Nehrkorn, T., J. Eluszkiewicz, S. C. Wofsy, J. C. Lin, C. Gerbig,
  M. Longo, and S. Freitas, 2010: Coupled weather research and
  forecasting - stochastic time-inverted lagrangian transport
  ({WRF-STILT}) model. Meteor. Atmos. Phys., 107 (1), 51-64,
  doi:10.1007/s00703-010-0068-x.

  For a discussion of how to choose parameters related to the
  computation of boundary layer height within STILT, refer to file:
  NWP/p1229/doc/pblh-instructions.txt.

3. For information on WRF (including copyright notices), refer to:

  http://www.mmm.ucar.edu/wrf/users/

  As of version 3.2.1, there is a known bug in dyn_em/start_em.F (a
  missing initialization line for variable f_flux).  Subdirectory
  NWP/WRFV3/dyn_em contains a corrected version of this routine, for
  version 3.2.1 of WRF.

4. For compiling and running the wrf netcdf to arl converter, see
  NWP/arl-format/Readme.txt.

  For typical WRF-STILT implementations, the output of the converter
  is organized into separate directories according to the valid time
  of the forecast files: for example, directory 20081123 would contain
  converted wrfout files, for all domains (dnn, as in d01, d02, d03,
  ...) valid from times past 06 UTC 23 Nov 2008 through 06 UTC 24 Nov
  2008.  These files are then concatenated into correspondingly named
  files (e.g., d01.20081123.arl, d02.20081123.arl, ...) using the
  script: NWP/p1564/bin/concat_arl.csh.

  The sample code in the Readme file, and the concat_arl.csh script,
  assume that separate times are written to separate netcdf wrfout
  files.  Netcdf files with multiple output times require an
  additional command-line argument to the wrfnc2arl program.
