> If a domain axis construct does not correspond to a continuous physical quantity, then it is not necessary for it to be associated with a dimension coordinate construct. For example, this is the case for an axis that runs over ocean basins or area types, or for a domain -axis that indexes a time series at scattered points. In such cases, -one-dimensional auxiliary coordinate constructs could be used to store -coordinate values. These axes are called "discrete" axes in CF-netCDF. +axis that indexes a time series at scattered points. These axes are +discrete axes in CF-netCDF.
