WRF/WPS 2016

Introduction

The WRF Preprocessing System (WPS) is a new software introduced in WRF V2.2, to replace the existing WRF SI. The static fields and grid domains are specified in the first program, geogrid (analagous to the SI gridgen program). The external analysis and forecast data are decoded from the Grib format with the ungrib program in WPS (similar to the grib_prep program in SI). The final program in the WPS suite is the metgrid program, which horizontally interpolates the data from ungrib (similar to the hinterp program in SI). The vertical interpolation has been moved to the real program under WRF.

In Version 3, WPS is the only pre-processing software supported.

Installed version

There are serveral version of WRF and WPS installed on the cluster:

WRF

• 3.6.1
• 3.7.1
• 3.8.0
• 3.8.1
• 3.9

WPS

• 3.6.1
• 3.7.1
• 3.8.0
• 3.9

Using WRF/WPS on the HPC cluster

If you want to use WRF or WPS on the HPC cluster, you will have to load the corresponding modules first. You can do that with the following command:

module load WRF (this will load version 3.9)

or

module load WPS (this will load version 3.9)

If you want to use a different version of WRF/WPS you will have to add the desired version to the module-load-command:

module load WRF/3.7.1

or

module load WPS/3.7.1
