WRF4_UoLeeds

Guidance on using WRF4 on the UoLeeds ARC3 & ARC4 system

This code repository contains ther following:

• Information on using prebuilt WRF executables on the University of Leeeds HPC system.

• Useful scripts such as GFS and ERA5 met data retrieval and example altered TBL files

• Copies of 2 files that are used to invoke an environment on the University of Leeds HPC for setting up an Evironment for an undergraduate teaching module in Practical Weather Forecasting.

  The files are:

  WRFv4_setup_env.sh - used to invoke the cemac module and set up some test environments for running the model;

  WRF_tidyup.sh - shell script used to clean up old WRF output files before performing a new case study

More details on how to invoke the WRF environment and run it on ARC3 are available here

Full details of the compilation method are available here. These notes may also be used as a guide by University of Leeds researchers who wish to build their own local instance of WRFv4 for model development work.

CEMAC WRF modules

To use available cemac modules please run:

. /nobackup/cemac/cemac.sh

or add the following lines to your .bashrc

if [[ $- =~ "i" ]]; then
    if [ -r /nobackup/cemac/cemac.sh ] ; then
	. /nobackup/cemac/cemac.sh
    fi
fi

WRFv3 and WRFv4 are available to load as stand alone modules via:

module load WRF/4.2

this will allow the user to run prebuilt wrf.exe real.exe and preprocessing tools etc. Copies of WRF source code, run directories and WPS files can be found in /nobackup/WRF/

a number of tools can also by loaded

• wrfconda - an anaconda environment containing python libraries such as wrf-python
• ncl
• ncview
• nco
• cdo
