By this point, there is generally no need to change any of the variables in the “share”<br />
namelist record, since those variables should have been suitably set in previous steps. If<br />
the "share" namelist was not edited while running geogrid and ungrib, however, the <strong>WRF</strong><br />
dynamical core, number of domains, starting and ending times, interval between<br />
meteorological data, and path to the static domain files must be set in the “share”<br />
namelist record, as described in the steps to run geogrid and ungrib.<br />
In the “metgrid” namelist record, the path and prefix of the intermediate meteorological<br />
data files must be given with fg_name, the full path and file names of any intermediate<br />
files containing constant fields may be specified with the constants_name variable, and<br />
the output format for the horizontally interpolated files may be specified with the<br />
io_form_metgrid variable. Other variables in the “metgrid” namelist record, namely,<br />
opt_output_from_metgrid_path and opt_metgrid_tbl_path, allow the user to<br />
specify where interpolated data files should be written by metgrid and where the<br />
METGRID.TBL file may be found.<br />
As with geogrid and the GEOGRID.TBL file, a METGRID.TBL file appropriate for the<br />
<strong>WRF</strong> core must be linked in the metgrid directory (or in the directory specified by<br />
opt_metgrid_tbl_path, if this variable is set).<br />
> ls metgrid/METGRID.TBL<br />
lrwxrwxrwx 1 15 METGRID.TBL -> METGRID.TBL.<strong>ARW</strong><br />
After suitably editing the namelist.wps file and verifying that the correct METGRID.TBL<br />
will be used, metgrid may be run by issuing the command<br />
> ./metgrid.exe<br />
If metgrid successfully ran, the message<br />
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!<br />
! Successful completion of metgrid. !<br />
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!<br />
will be printed. After successfully running, metgrid output files should appear in the WPS<br />
root directory (or in the directory specified by opt_output_from_metgrid_path, if this<br />
variable was set). These files will be named met_em.d0N.YYYY-MM-DD_HH:mm:ss.nc in<br />
