Description

I haven't looked at this too closely but it appears that this is a way to save MultiIndexed datasets to netCDF. So we may be able to do sparse -> multiindex -> netCDF

Research direction

Start by reading the linked CF conventions section and tracing xarray’s existing MultiIndex and netCDF handling. Check whether the proposed sparse → MultiIndex → netCDF path is supported, and define the smallest reproducible case needed to demonstrate it. Done means a confirmed implementation path or a clearly scoped limitation, with a test or example for the supported behavior.
