Function latlon_coordvars

src/wrf/util.py:275–306

Return the first found latitude and longitude coordinate names from a NetCDF variable dictionary. This function searches the dictionary structure for NetCDF variables and returns the first found latitude and longitude coordinate names (typically 'XLAT' and 'XLONG'). Args:

(ncvars)
