calmet_define_geophys: Define the CALMET domain and generate a geophysical input...
In rich-iannone/PuffR: A set of tools to help with CALPUFF dispersion modelling.

Description Usage Arguments Examples

Define the CALMET domain and determine the best gridded values for land use, terrain heights, and micrometeorological parameters for creation of a geophysical input file.

calmet_define_geophys(location_name, lat_dec_deg = NULL, lon_dec_deg = NULL,
  lat_lon_grid_loc = 1, domain_width_m = NULL, domain_height_m = NULL,
  cell_resolution_m = 250, four_seasons = TRUE,
  four_season_breaks = c("03-15", "05-31", "08-31", "11-15"),
  LU_method = "MODIS_Global", shapefile_dir = NULL)

`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.
