Description of METGRID.TBL Options
The METGRID.TBL file is a text file that defines parameters of each of the
meteorological fields to be interpolated by metgrid. Parameters for each field are defined
in a separate section, with sections being delimited by a line of equality symbols (e.g.,
‘==============’). Within each section, there are specifications, each of which has
the form of keyword=value. Some keywords are required in a section, while others are
optional; some keywords are mutually exclusive with other keywords. Below, the
possible keywords and their expected range of values are described.
1. NAME : A character string giving the name of the meteorological field to which the
containing section of the table pertains. The name should exactly match that of the field
as given in the intermediate files (and, thus, the name given in the Vtable used in
generating the intermediate files). This field is required. No default value.
2. OUTPUT : Either yes or no, indicating whether the field is to be written to the metgrid
output files or not. Default value is yes.
3. MANDATORY : Either yes or no, indicating whether the field is required for
successful completion of metgrid. Default value is no.
4. OUTPUT_NAME : A character string giving the name that the interpolated field
should be output as. When a value is specified for output_name, the interpolation options
from the table section pertaining to the field with the specified name are used. Thus, the
effects of specifying output_name are two-fold: The interpolated field is assigned the
specified name before being written out, and the interpolation methods are taken from the
section pertaining to the field whose name matches the value assigned to the
output_name keyword. No default value.
