__init__(**proj_params)

Initialize a wrf.LatLon object.

Parameters:

**proj_params –

Map projection optional keyword arguments, that have the same names as found in WRF output NetCDF global attributes:

• ’TRUELAT1’: True latitude 1.

• ’TRUELAT2’: True latitude 2.

• ’MOAD_CEN_LAT’: Mother of all domains center latitude.

• ’STAND_LON’: Standard longitude.

• ’POLE_LAT’: Pole latitude.

• ’POLE_LON’: Pole longitude.
