module load cray-netcdf-hdf5parallel/4.9.0.7
module load cray-parallel-netcdf/1.12.3.7
module load libpng/1.6.3739-cpeIntel-23.0309
module load JasPer/1.900.1-cpeIntel-23.0309
module load flex/2.6.4

3. Download WRF source code

An example for WRF 4.5.1 is as shown below.

Code Block
languagebash
cd $DIR
wget https://github.com/wrf-model/WRF/releases/download/v4.5.1/v4.5.1.tar.gz
tar xzf v4.5.1.tar.gz
mv WRFV4.5.1 WRF
Note

Some chemistry options may be incompatible with the most recent WRF release. Users may need to compile WRF-Chem using older versions.
