Just so we're all using the same terminology, you are actually referring to ""coordinates"", not dimensions. In your example above, `tss` is getting the correct dimension (`time2`) but the corresponding coordinate (`time2`) is not loaded. In netCDF/xarray dimensions are just names for individual axes.

The fundamental issue is that we don't have any machinery in xarray to look outside of a single netCDF group when opening a dataset. That is the common piece to #1092.

The short answer is that we don't have a first class solution to working with groups in netCDF files. ,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,304314787
