Build process

1. Get the source code

   wget http://www2.mmm.ucar.edu/wrf/src/WRFV3.7.TAR.gz
   tar xvf WRFV3.7.TAR.gz
   cd WRFV3
   

2. Load the necessary modules

   module load gcc/5.4.0
   module load mpich2/3.2_gcc-5.4.0
   module load jasper/1.900.1_gcc-5.4.0
   module load autoconf/2.69
   module load hdf5/1.8.16_gcc-5.4.0
   module load netcdf-fortran/4.4.3_gcc-5.4.0
   module load zlib/1.2.11_gcc-5.4.0
   

3. Execute the configuration script.

   ./configure
   checking for perl5... no
   checking for perl... found /usr/bin/perl (perl)
   Will use NETCDF in dir: /usr/bin/netcdf
   HDF5 not set in environment. Will configure WRF for use without.
   PHDF5 not set in environment. Will configure WRF for use without.
   Will use 'time' to report timing information
   $JASPERLIB or $JASPERINC not found in environment, configuring to build without grib2 I/O...

   Compile for nesting? (1=basic, 2=preset moves, 3=vortex following) [default 1]: 1

   The configuration file is configuration.wrf.

4. Compile WRF, with the case you need.

   ./compile <case> | tee wrf-compilation.log
   

   In main/ you should see the following executables:

   • If you compile a real case:

     wrf.exe
     real.exe
     ndown.exe
     tc.exe
     

   • If you compile an idealized case

     wrf.exe
     ideal.exe
     

Compile WSP

The WRF Preprocessing System (WPS) [1] is a set of three programs whose collective role is to prepare input to the real.exe program for real-data simulations.

1. Download the latest version of WSP

   wget https://github.com/wrf-model/WPS/archive/v3.7.tar.gz
   tar vf 3.7.tar.gz
   cd WPS-3.7
   

2. Load the correspondent modules and execute the configuration script.

   module load jasper
   ./configure
   

3. Edit the configuration file configure.wps

   WRF_DIR = path/to/wps
   
   // Depends on your compiler version you should remove -f90=ifort from the following line
   DM_FC = mpif90 -f90=ifort
   

4. Compile it.

   ./compile | tee wps-compilation.log
   

Modulefile

WRF must be installed locally in the user’s home because of that, there is no module file.
