Hi King,
I think that your type of dataset isn't supported at the moment, due to the
presence of 2D non-independent coordinate variables.
https://docs.geoserver.org/stable/en/user/extensions/netcdf/netcdf.html#notes-on-supported-netcdfs
Scroll down that paragraph to the 2nd screenshot with ToolsUI. Based on
what I see from your ncml output that screenshoot looks very similar to
your situation.
Regards,
Daniele
