1. Load required modules and set environment variables
Paste the below lines into your terminal. (Putting these in ~/.bashrc is not recommended.)
| Code Block | ||
|---|---|---|
| ||
module purge module load cpeIntel/23.0309 module load cray-hdf5-parallel/1.12.2.7 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 module load ADIOS2/2.9.1-cpeIntel-23.09 export WRF_EM_CORE=1 # Explicitly select ARW core developed by NCAR export WRF_NMM_CORE=0 # Not NMM core export WRF_DA_CORE=0 # Not WRFDA export WRF_CHEM=1 # Select WRF-Chem export NETCDF=${CRAY_NETCDF_HDF5PARALLEL_PREFIX} export NETCDFPAR=${CRAY_NETCDF_HDF5PARALLEL_PREFIX} export PNETCDF=${CRAY_PARALLEL_NETCDF_PREFIX} export HDF5=${CRAY_HDF5_PARALLEL_PREFIX} export JASPERINC=${EBROOTJASPER}/include # (Optional) export JASPERLIB=${EBROOTJASPER}/lib # (Optional) export ADIOS2=${EBROOTADIOS2} export WRFIO_NCD_LARGE_FILE_SUPPORT=1 # (Optional) export PNETCDF_QUILT=1 # (Optional) export WRF_KPP=1 export FLEX=flex export FLEX_LIB_DIR=${EBROOTFLEX}/lib export YACC='/usr/bin/yacc -d' ### Common mistake :: insert spaces before or after = |

3. Download WRF source code
An example for WRF 4.5.1 is as shown below.
| Code Block | ||
|---|---|---|
| ||
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. |
...
| Note |
|---|
Must set JASPERINC and JASPERLIB in Step 1 |
| Warning |
|---|
GRIB2 IO is now deprecated in WRF 4.6.X. |
Open ${DIR}/WRF/arch/Config.pl (or Config_new.pl) using a text editor such as vi
Change the parameter
$I_really_want_to_output_grib2_from_WRFfrom"FALSE"to"TRUE"
| Code Block | ||
|---|---|---|
| ||
vi ${DIR}/WRF/arch/Config.pl # or Config_new.pl
# Change $I_really_want_to_output_grib2_from_WRF = "FALSE" ;
# to $I_really_want_to_output_grib2_from_WRF = "TRUE" ; |
5. Configure
| Expand | ||
|---|---|---|
| ||
Note: It is alright to do Step 2, because the cause was from using the wrong compiler wrappers that are fixed in Step 5. |
5.1 Run ./configure
| Code Block | ||
|---|---|---|
| ||
cd ${DIR}/WRF
./configure
# Type 50, then press Enter <-- (dmpar) INTEL (ftn/icc): Cray XC
# Type 1, then press Enter <-- Basic nesting |

| Note |

CONVERT_EMISS of some WRF releases could cause an unexpected segmentation fault at runtime (see this and this). CONVERT_EMISS of WRF 3.6.1 and 4.5.X are recommended. |
