# WRF configuration

To use WRF model in WRF4G2.0, you have to configure app variable in the experiment.wrf4g file. By default, WRF4G2.0 provides a bundle with all you need to simulate an WRF experiment, configure as follows :

app = wrf_all_in_one | bundle | /home/user/wrf4g/repository/apps/WRF/WRFbin-3.4.1_r2265_gfortran.tar.gz


This bundle is able to be used for any x86_64 Linux system, and contains binaries, libraries and configuration files for WRF-3.4.1 build against gfortran-4.4.7, openmpi-1.4.3 and netcdf-4.1.3, which are include in the bundle too.

But, if you want to use your own WRF installed on your machine or on a cluster, you have to update the app variable. There are several ways to configure this variable depending on your WRF configuration system. In order to clarify that, we are going to write some examples:

• Using module command:
app =   wps | command | module load wps/4.5.1
wrf | command | module load wrf/4.5.1


We assume that each command is configuring other softwares such as openmpi

• Using PATH and LD_LIBRARY_PATH shell variables:
