There is no such thing as a "multidimensional DataArray" in the xarray data model. DataArrays can have "non-dimension coordinates" which can be used for things like grouping.

This would work python new_array = DataArray(np.zeros((2,2)), dims=['x_logical','y_logical']) new_array.coords['x_physical'] = x_physical new_array.coords['y_physical'] = y_physical new_array.groupby('x_physical').mean()

I don't know how to do this as a one-liner. Probably easier to create a Dataset rather than DataArray for this purpose python ds = xr.Dataset({'testdata': (('y_logical', 'x_logical'), np.zeros((2,2)))}, coords={'x_physical': (('y_logical', 'x_logical'), np.ones((2,2))), 'y_physical': (('y_logical', 'x_logical'), np.ones((2,2)))})
