instead of using the Dataset constructor it's actually better to manually convert to a Dataset before passing to xr.merge: ```python arr1 = xr.DataArray([0, 1], dims="x", attrs={"units": "m"}, name="a") arr2 = xr.DataArray([2, 3, 4], dims="y", attrs={"units": "s"})

xr.merge([arr1.to_dataset(), arr2.to_dataset(name="b")], ...) `` that way, the merge is configurable but we avoid thepromote_attrs=True`
