  • standard names: names present in standard_name attribute of coordinate variables

  • cf roles: ‘timeseries_id’, ‘profile_id’, ‘trajectory_id’, ‘mesh_topology’, ‘grid_topology’

Returns
DataArray
Raises
KeyError

DataArray.cf[List[str]] will raise KeyError.

Notes

Associated CF variables will be attached as coordinate variables by parsing attributes such as cell_measures, coordinates etc.
