Ghansham, I do not have a sample dataset with a discrete axis that I can think of offhand. If you were to create a new dimension (axis) for aggregation using NcML, you would do it as described here: http://www.unidata.ucar.edu/software/netcdf/ncml/v2.2/Aggregation.html#joinNew Note that you would not be able to do this inside of a single dataset, per your original question.
