I think it is clearly mentioned in the documentation that NetCDF with 2D lat/lon are supported by GeoServer: https://docs.geoserver.org/stable/en/user/extensions/netcdf/netcdf.html#two-dimensional-coordinate-variables
I am looking for a sample NetCDF datafile with 2D coordinates (mentioned in documentation) to play with in GeoServer. My own datafiles (with 2D lat/lon) cannot be read by GeoServer.
