WRF4G files

WRF4G files is a directory, called wrf4g_files, located in the same directory where experiment.wrf4g is. Under this directory you can create a tree directory as follows :

├── bin
│   ├── preprocessor.default
│   └── postprocessor.SFC
├── lib
├── lib64
├── WPS
│   ├── configure.wps
│   ├── link_grib.csh
│   ├── link_grib.sh
│   ├── metgrid
│   │   └── METGRID.TBL
│   └── ungrib
│       └── Variable_Tables
│           ├── Vtable.AFWAICE
│           ├── Vtable.AGRMETSNOW
│           ├── Vtable.AGRMETSOIL
│           ├── Vtable.AGRMETSOIL2
│           ....
└─── WRFV3
   └── run
       ├── CAM_ABS_DATA
       ├── CAM_AEROPT_DATA
       ├── co2_trans
       ├── ETAMPNEW_DATA
       ├── ETAMPNEW_DATA_DBL
       ├── ozone.formatted
       ├── ozone_lat.formatted
       ....

Therefore, you can put your preprocessors and postprocessors under bin directory, or you can add WPS and WRF configuration files (e.g. Variable_Tables,CAM_ABS_DATA, ETAMPNEW_DATA_DBL, etc ) for WRF model. This directory is packed and used on each WRF4G run realization.
