WRF-CTSM Tools and Utilities
|
||
=============================
|
||
|
||
This section includes instructions on tools and utilities developed for
|
||
WRF-CTSM simulations.
|
||
|
||
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.
|
||
|
||
1. Create SCRIP grid file from WRF ``geo_em*`` files, using the following ncl
|
||
script::
|
||
|
||
ncl create_scrip_file.ncl
|
||
|
||
This creates two files that are complements of each other only in the mask field
|
||
|
||
2. Create mapping files by using ``mkmapdata`` code under
|
||
``CTSM/tools/mkmapdata/``.
|
||
|
||
Using environment variables set the following environment varibales needed
|
||
by ``mkunitymap.ncl`` code::
|
||
|
||
setenv GRIDFILE1 wrf2clm_ocean_noneg.nc
|
||
setenv GRIDFILE2 wrf2clm_land_noneg.nc
|
||
setenv MAPFILE wrf2clm_mapping_noneg.nc
|
||
setenv PRINT TRUE
|
||
|
||
ncl mkunitymap.ncl
|
||
|
||
.. warning::
|
||
|
||
This will throw some git errors if not run in a repository.
|
||
|
||
3. Create ESMF mapping files by running ``regridbatch.sh``::
|
||
|
||
qsub regridbatch.sh
|
||
|
||
4. In your ctsm repository directory, build::
|
||
|
||
../../../configure --macros-format Makefile --mpilib mpi-serial
|
||
|
||
5. Generate CTSM domain files using ``get_domain`` tool::
|
||
|
||
./gen_domain -m /glade/work/$USER/ctsm/nldas_grid/scrip/wrf2clm_mapping_noneg.nc -o wrf2clm_ocn_noneg -l wrf2clm_lnd_noneg
|
||
|
||
6. Create surface datasets in ``tools/mksurfdata_esmf``::
|
||
|
||
./mksurfdata.pl -res usrspec -usr_gname "nldas" -usr_gdate "190124" -usr_mapdir "/glade/work/$USER/ctsm/nldas_grid/map" -y 2000 -exedir "/glade/u/home/$USER/src/ctsm/ctsm_surfdata/tools/mksurfdata_esmf" -no-crop
|
||
|
||
Merge WRF initial conditions into an existing CTSM initial condition file
|
||
--------------------------------------------------------------------------
|
||
|
||
The following procedure is if you'd wish to merget WRF inital conditions from
|
||
``wrfinput`` file into CTSM initial condition file ::
|
||
|
||
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::
|
||
|
||
Sam, can you please make the above ncl script available.
