Installation
==========================================================================
This inline HYSPLIT was compiled on aikten.arl.noaa.gov.
The installation is the same as the standard WRF (WRF version 3.7).

Run the "run.replace" script by providing the path of your WRF directory. 
This script copies modified and newly added files to your WRF directory. 
Clean up the model, configure and compile like installing a standard WRF. 

./clean -a
./configure
   The option for configure.wrf (on ARL's byun machine):
   15. (dmpar) INTEL (ifort/icc)
./compile em_real >& log &

==========================================================================
Input and output files
==========================================================================
Input files for running WRF - wrfinput, wrfbdy
                              wrffdda (optional for grid nudging)

Namelist files - CONTROL (same format as the standard HYSPLIT)
                 namelist.input (including &hysplit section)
                 EMITIMES (optional for HYSPLIT emission)
                 addfields.txt (optional for running trajectory)

Output files
cdump - default HYPSLIT output
        tracer concentration in lat/lon coordinate
hycsum - extra variable in wrfout files, 
         tracer concentration in WRF grid (not fully evaluated)

For trajectory run, namelist.input should include the following line 
in $time_control that position info (lat/lon/height) of trajectory 
will be written out in wrfout files.
 iofields_filename                   = "addfields.txt"

====================================================================================
Testcase - CAPTEX #2
====================================================================================
IC/BC files of CAPTEX #2 for running WRF (incduling wrfinput, wrfbdy and wrffdda)
are in captex2-icbc/. All namelist files for running inline HYSPLIT are in 
captex2-setup/. Cases are listed below:

1) c2reg  - regular dispersion run for CAPTEX #2 
2) drydep - dispersion with dry deposition
3) wetdep - dispersion with wet depostion
4) rad    - dispersion with radioactive decay
5) traj   - trajectory run
