That's rather annoying that the pint units are dropped: python arr = xr.DataArray( name="var_a", data=np.array([[1, 2], [3, 4]]), # TODO make coord a Quantity once unit-aware indexes supported coords=dict( a=("a", pint.Quantity(np.array([5, 6]), "s")), b=("b", np.array([7, 8]), {"unit": "s"}), ), dims=("a", "b"), ) C:\Users\J.W\Documents\GitHub\xarray\xarray\core\utils.py:118: UnitStrippedWarning: The unit of the quantity is stripped when downcasting to ndarray. index = pd.Index(np.asarray(array), **kwargs) I think xarray could've at least moved the pint unit string to arr.a.attrs["units"] before downcasting it to ndarrays.
