3.4.3. WRF-CTSM Tools and Utilities

This section includes instructions on tools and utilities developed for WRF-CTSM simulations.

3.4.3.1. Generate CTSM surface dataset for a WRF domain

Before this step, make sure you have successfully created geo_em* files for your specific WRF domain using WPS. Instructions on how to run geogrid.exe is described in here.

Create ESMF mesh file from WRF geo_em* files, using the make_mesh tool. Details in section 1.9.1.
Create surface datasets in tools/mksurfdata_esmf. Details in section 1.3.4.

3.4.3.2. Merge WRF initial conditions into an existing CTSM initial condition file

The following procedure is if you'd wish to merge WRF inital conditions from wrfinput file into CTSM initial condition file

module load ncl
ncl transfer_wrfinput_to_ctsm_with_snow.ncl 'finidat="the_existing_finidat_file.nc"' 'wrfinput="your_wrfinput_file"' 'merged="the_merged_finidat_file.nc"'

Todo

Versions of the transfer_wrfinput ncl script are available in /glade/work/slevis/git_wrf/ctsm_init/.
