gen_domain to create a domain file for datm from a mapping file. The domain file is then used by BOTH DATM AND CLM to define the grid and land-mask. The general data flow is shown in two figures. Figure 2-4 shows the general flow for a general global case (or for a regional grid that DOES include ocean). Figure 2-5 shows the use of mknoocnmap.pl (see the Section called Using mknocnmap.pl to create grid and maps for single-point regional grids) to create a regional or single-point map file that is then run through gen_domain to create the domain file for it. As stated before Figure 2-2 is the legend for both of these figures. See the tools/mapping/gen_domain_files/README file for more help on gen_domain.
Here we create domain files for a regular global domain.
Note, that the SCRIP grid file used to start this process, is also used in mkmapdata.sh (see the Section called Creating mapping files that mksurfdata_map will use). Next we create domain files for a single-point or regional domain. In this case the process creates both SCRIP grid files to be used by mkmapdata.sh as well as the domain files that will be used by both CLM and DATM.
