I found this problem too long ago (see #457). Back then the workaround we implemented is to exclude the offending variable ("siglay" or "isobaric" in the examples above) with the "drop_variables" optional argument. Of course this is not great if you want to actually use the values in the variable you are dropping.

I personally don't like the notion of a "two dimensional coordinate", I find it confusing. However this kind of netCDFs are common, so fully supporting them in xarray would be nice. But I don't know how. Maybe just renaming the variable instead of dropping it with a "rename_variables"? This is the only thing that comes to my mind.
