WRF V4. & WRF-Cordex Manual

1. Setting Environment

This is describing the steps to install all the requried environment for compilation of the WRF& WPS. All the requred libraries and its installation process was written in the shell script within folder library_installation:

• 1lib.sh : to install packages for installation
• 2lib.sh : to download and unzip all neccessary libraries
• 3lib.sh : to install NetCDF, mpich, zlib, libpng, and jasper library
• 4lib.sh : to download and install NCL and Gfortran
• getwrf.sh : to download WRF&WPS from GitHub Repository, and WRF cordex

2. WRF& WPS Compilation

You need to make sure that you have installed all the required libraries correctly, especially NetCDF library. After that start compiling WRF with following steps and procedure.

• tar xvfz WRFV4.0_CORDEX.tar.gz
• Edit the Registry/Registry.EM and add the line include 'registry.cordex' after the line ‘registry.em_shared_collection’
• Inside WRF/ directory type:
  • ./clean
  • ./configure, then choose
  • GNC(gfortran/gcc) = 34(dmpar)
  • compile for nesting = 1-basic
  • Edit the configure.wrf file by adding - DCORDEXDIAG after - DNETCDF
  • ./compile em_real >& log.compile
• If the compilation is successful, you should find these executables in WRF/main (non zero size)
  • wrf.exe model executable
  • real.exe real data initialization
  • ndown.exe one way nesting
  • tc.exe for tc bogusing (serial only)
• Inside WPS/ directory type:
  • ./configure
  • select 3(dmpar) for compilation
  • ./compile >& log.compile
• If successful, these executables should be in your WPS/ directory (and they are linked, respectively, from their source code directories):
  • geogrid.exe --> geogrid src geogrid.exe
  • ungrib.exe --> ungrib src ungrib.exe
  • metgrid.exe --> metgrid src metgrid.exe
