I think SO is the best place for user Qs, so the answers can be searchable for future generations.

To respond immediately though, have you tried .squeeze? Or, to confirm, you actually want to remove a rather than b here?

```python In [1]: import xarray as xr

In [2]: test_dataset = xr.Dataset(dict( ...: empty_array=xr.DataArray([], dims='a'), ...: populated_array=xr.DataArray([1], {'b':['1']}, 'b') ...: ))

In [3]: test_dataset Out[3]: <xarray.Dataset> Dimensions: (a: 0, b: 1) Coordinates: * b (b) <U1 '1' Dimensions without coordinates: a Data variables: empty_array (a) float64 populated_array (b) int64 1

In [4]: test_dataset.squeeze() Out[4]: <xarray.Dataset> Dimensions: (a: 0) Coordinates: b <U1 '1' Dimensions without coordinates: a Data variables: empty_array (a) float64 populated_array int64 1 ```
