Obtain surface meteorology and generate input files

calmet_surface_met(location_name, year, 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, time_offset,
  local_archive_dir = NULL, use_CSV_files = NULL)

`location_name`	an assigned name for the CALMET domain.
`year`	the year for the SURF.DAT file.
`lat_dec_deg`	the latitude of the CALMET domain in decimal degrees. The location of this point is defined in the lat_long_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_long_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 width of the meteorological domain in meters.
`domain_height_m`	the height of the meteorological domain in meters.
`cell_resolution_m`	the grid cell resolution in meters.
`time_offset`	the offset from UTC-00:00 in hours.
`local_archive_dir`	a local path containing an archive of gzipped NCDC station data files.
`use_CSV_files`	option to use local, pre-processed CSV files.
