How to get WRF4G

The latest official version can get it by direct download WRF4G.tar.gz. Before you get it, you have to check the WRF4G requirements:

  • x86_64 Linux
    [user@localhost ~]$ uname -p
    x86_64
    
  • Python, version >= 2.4 and < 3.0
    [user@localhost ~]$ python -V
    Python 2.7.3
    

See the installation guide for moreover information.

Quick deploy guide

Deploy WRF4G

Download and unpack the distribution file into the deployment directory (e.g. $HOME directory).

[user@localhost ~]$ cd 
[user@localhost ~]$ wget http://www.meteo.unican.es/work/WRF4G.tar.gz
[user@localhost ~]$ tar xzvf WRF4G.tar.gz

Setup the WRF4G environment.

[user@localhost ~]$ export PATH=$HOME/WRF4G/bin:$PATH

In order to avoid typing the export command every time you open a terminal, you should copy it into $HOME/.bashrc.

[user@localhost ~]$ echo "export PATH=$HOME/WRF4G/bin:$PATH" >> $HOME/.bashrc

Verifying

You can verify if WRF4G has been deployed properly by running the following command:

[user@localhost ~]$ wrf4g_framework start
Starting DRM4G (GridWay) .... OK
Starting WRF4G_DB (MySQL) ... OK

If the answers are not satisfactory ("OK"), you should check out the log files:

  • $HOME/WRF4G/opt/drm4g_gridway/var/gwd.log for DRM4G (GridWay)
  • $HOME/WRF4G/var/mysql.log for WRF4G_DB (MySQL).
