cf.Index.nc_sample_dimension_groups

Index.nc_sample_dimension_groups()

Return the netCDF sample dimension 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.
