WRF-CHEM (version 3.5.1) Installation


Source Code


The source code tar files of WRF, WRF-CHEM, and WPS (V3.5.1) have been downloaded and placed in the subdirectory /projects/WRF/Downloads on the RAIJIN cluster. The uncompressed source code for V3.5.1 of WRF (including WRF-CHEM) and WPS, which have been ported to build on RAIJIN cluster, is located in the subdirectory /projects/WRF/WRFV_3.5.1_Chem.

How to build WRF-Chem V3.5.1


Make a copy of the WRF-CHEM source, which you can find on Raijin at /projects/WRF/WRFV_3.5.1_Chem

If you wish to use the Kinetic Pre-Processor (KPP) run the following commands:
#bash
export WRF_KPP=1
export FLEX_LIB_DIR=/usr/lib64
export YACC="/usr/bin/yacc -d"

You can then configure and submit the build to the queue. Note that you first need to set some additional environment variables to turn on the EM core and chemistry
# bash
module load intel-fc
module load openmpi
module load netcdf
 
export WRFIO_NCD_LARGE_FILE_SUPPORT=1
export EM_CORE=1
export WRF_CHEM=1
 
./configure
 
# Answer ./configure questions as normal...
 
qsub -q express -v PROJECT,WRF_CHEM,EM_CORE run_compile

How to make a WRF-Chem test run


Sample Data Set


A sample data set from GFS has been placed in /projects/WRF/data/wrfchem-tut/GFS for doing a test run.

Running WPS


The instruction is the same as here except below:
cd WPS
rm -f Vtable
ln -s ungrib/Variable_Tables/Vtable.GFS .
mv namelist.wps namelist.wps.bak
cp namelist.wps.chem namelist.wps
./link_grib.csh /projects/WRF/data/wrfchem-tut/GFS/*
