cfdm.AuxiliaryCoordinate.nc_node_coordinate_variable_groups

AuxiliaryCoordinate.nc_node_coordinate_variable_groups()

Return the netCDF node coordinate variable group hierarchy.

The group hierarchy is defined by the netCDF name. Groups are delimited by / (slash) characters in the netCDF name. The groups are returned, in hierarchical order, as a sequence of strings. If the name is not set, or contains no / characters then an empty sequence is returned, signifying the root group.

New in version (cfdm): 1.11.0.0
