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>

    b                <U1 '1'
