WRF Versions

There are various WRF versions available on POD. Use the module command to see the available versions. If you need any additional versions installed, please email pod@penguincomputing.com.

[penguin@podmt1 ~]$ module avail wrf

----------------------------- /public/modulefiles ------------------------------
wrf/3.5/gcc.4.4.7      wrf/3.5/intel.12.1.0   wrf/3.5.1/intel.12.1.0


WRF Example

A sample submission script is available at /public/examples/wrf-examples/wrf_example_1.sub. This is a self contained script that runs the default January 2000 case illustrated in the official WRF tutorial. To run the sample:

[penguin@podmt1 ~]$ mkdir test_wrf
[penguin@podmt1 ~]$ cp /public/examples/wrf-examples/wrf_example_1.sub test_wrf
[penguin@podmt1 ~]$ cd test_wrf
[penguin@podmt1 ~]$ qsub wrf_example_1.sub

To set up a working directory for running WPS + WRF + UPP from the public install, use the POD WRF utility script called build_wrf_workdir. This script takes a directory name as parameter and creates the appropriate folder structure for running WPS and WRF:

[penguin@podmt1 ~]$ module load wrf/3.5.1/intel.12.1.0
[penguin@podmt1 ~]$ mkdir test_wrf
[penguin@podmt1 ~]$ build_wrf_workdir test_wrf
[penguin@podmt1 ~]$ ls test_wrf
UPPV2.1    WPS   WRFV3


Geogrid Data

Geogrid data for all available resolutions (30”, 2’, 5’ and 10’) are available in /public/apps/wrf/WPS_GEOG. The ‘geog_data_path’ field of WRF's namelist.wps has already been configured to use this geogrid data.

[penguin@podmt1 ~]$ ls /public/apps/wrf/WPS_GEOG
