Thanks for the reply. Would it make things easier if c, d = xr.align(a, b, join="outer") explicitly broadcasts missing dimensions in all returned values? Currently, if b is missing a dimension, then d would also miss a dimension:

```

a <xarray.DataArray (x: 2, y: 2)> array([[1, 1], [1, 1]]) Coordinates: * x (x) |S1 'a' 'b' * y (y) int64 -2 0 b <xarray.DataArray (x: 3)> array([4, 5, 6]) Coordinates: * x (x) |S1 'a' 'b' 'd' c, d = xr.align(a, b, join="outer") c <xarray.DataArray (x: 3, y: 2)> array([[ 1., 1.], [ 1., 1.], [ nan, nan]]) Coordinates: * x (x) object 'a' 'b' 'd' * y (y) int64 -2 0 d <xarray.DataArray (x: 3)> array([4, 5, 6]) Coordinates: * x (x) object 'a' 'b' 'd' ```
