shared/mkmapdata to create SCRIP mapping data file from SCRIP grid files (uses ESMF).
The bash shell script models/lnd/clm/tools/shared/mkmapgrids/mkmapdata.sh uses ESMF_RegridWeightGen to
create a list of maps from the raw datasets that are input to mksurfdata_map. Each dataset that
has a different grid, or land-mask needs a different mapping file for it, but many different raw datasets share
the same grid/land-mask as other files. Hence, there doesn't need to be a different mapping file for EACH raw
dataset -- just for each DIFFERENT raw dataset. See Figure 2-3 for a visual representation
of how this works. The bash script figures out which mapping files it needs to create
and then runs ESMF_RegridWeightGen for each one. You can then either enter the datasets into the XML database (see
Chapter 3 or leave the files in place, and use the "-res usrspec -usr_gname -usr_gdate"
options to mksurfdata_map (see the Section called Running mksurfdata.pl below). Use the "-phys" option
to specify if you are creating mapping files for clm4_0 or clm4_5 (the list of raw datafiles is somewhat different
between the two). mkmapdata.sh has a help option with the following
../../tools/shared/mkmapdata/mkmapdata.sh
**********************
usage on yellowstone:
./mkmapdata.sh
valid arguments:
[-f|--gridfile <gridname>]
Full pathname of model SCRIP grid file to use
This variable should be set if this is not a supported grid
This variable will override the automatic generation of the
filename generated from the -res argument
the filename is generated ASSUMING that this is a supported
grid that has entries in the file namelist_defaults_clm.xml
the -r|--res argument MUST be specied if this argument is specified
[-r|--res <res>]
Model output resolution (default is 10x15)
[-t|--gridtype <type>]
Model output grid type
supported values are [regional,global], (default is global)
[-p|--phys <CLM-version>]
Whether to generate mapping files for clm4_0 or clm4_5
supported values are [clm4_0,clm4_5], (default is clm4_5)
[-b|--batch]
Toggles batch mode usage. If you want to run in batch mode
you need to have a separate batch script for a supported machine
that calls this script interactively - you cannot submit this
script directory to the batch system
[-l|--list]
List mapping files required (use check_input_data to get them)
also writes data to clm.input_data_list
[-d|--debug]
Toggles debug-only (don't actually run mkmapdata just echo what would happen)
[-h|--help]
Displays this help message
[-v|--verbose]
Toggle verbose usage -- log more information on what is happening
You can also set the following env variables:
ESMFBIN_PATH - Path to ESMF binaries
(default is /contrib/esmf-5.3.0-64-O/bin)
CSMDATA ------ Path to CESM input data
(default is /glade/p/cesm/cseg/inputdata)
MPIEXEC ------ Name of mpirun executable
(default is mpirun.lsf)
REGRID_PROC -- Number of MPI processors to use
(default is 8)
**pass environment variables by preceding above commands
with 'env var1=setting var2=setting '

Caution |
Make sure you specify with the "-phys" option if you are creating files for CLM4.0! The default
is CLM4.5.
