Adding another example. While working through the Model Evaluation Tool (MET) tutorial, I created a NetCDF file with the tool, and wasn't able to open the file it created.

MissingDimensionsError: 'lat' has more than 1-dimension and the same name as one of its dimensions ('lat', 'lon'). xarray disallows such variables because they conflict with the coordinates used to label dimensions.

Sounds to me like the same error caused by https://github.com/pydata/xarray/issues/2233

Below is the .nc file contents with ncdump

```

ncdump sample_fcst_24L_2005080800V_12A.nc -h netcdf sample_fcst_24L_2005080800V_12A { dimensions: lat = 129 ; lon = 185 ; variables: float lat(lat, lon) ; lat:long_name = "latitude" ; lat:units = "degrees_north" ; lat:standard_name = "latitude" ; float lon(lat, lon) ; lon:long_name = "longitude" ; lon:units = "degrees_east" ; lon:standard_name = "longitude" ; float APCP_12(lat, lon) ; APCP_12:name = "APCP_12" ; APCP_12:long_name = "Total precipitation" ; APCP_12:level = "A12" ; APCP_12:units = "kg/m^2" ; APCP_12:_FillValue = -9999.f ; APCP_12:init_time = "20050807_000000" ; APCP_12:init_time_ut = "1123372800" ; APCP_12:valid_time = "20050808_000000" ; APCP_12:valid_time_ut = "1123459200" ; APCP_12:accum_time = "120000" ; APCP_12:accum_time_sec = 43200 ;
