location_name
an assigned name for the CALMET domain.
lat_dec_deg
the latitude of the CALMET domain in decimal degrees. The location of this point is defined in the lat_lon_grid_loc argument.
lon_dec_deg
the longitude of the CALMET domain in decimal degrees. The location of this point is defined in the lat_lon_grid_loc argument.
lat_lon_grid_loc
the location of the lat/long inputs in relation to the domain. Choices are: 1 (center), 2 (lower left), 3 (lower right), 4 (upper left), 5 (upper right).
domain_width_m
the desired width of the meteorological domain in meters.
domain_height_m
the desired height of the meteorological domain in meters.
cell_resolution_m
the desired cell resolution in meters.
four_seasons
an option for whether to split the generated GEO.DAT into four separate files, one for each of four seasons.
four_season_breaks
a character vector (in the format MM-DD) that specifies when the different seasons are to transition to the next.
LU_method
the method for obtaining CALMET land use codes for the selected domain; current options are (1) "MODIS_Global" and (2) "BTM_BC" (a method specific to the province of British Columbia in Canada, and, requires a local copy of the BC BTM V1 shapefile).
shapefile_dir
if the chosen 'LU_method' requires the use of a local shapefile (currently, the "BTM_BC" uses shapefile data), supply the relative or absolute path to the shapefile here.
