          coords : dict, optional
              Mapping from dimension names to the new coordinates.
              new coordinate can be an scalar, array-like or DataArray.
              If DataArrays are passed as new coordates, their dimensions are
              used for the broadcasting.
          method: {'linear', 'nearest'} for multidimensional array,
              {'linear', 'nearest', 'zero', 'slinear', 'quadratic', 'cubic'}
              for 1-dimensional array.
          assume_sorted: boolean, optional
              If False, values of x can be in any order and they are sorted
              first. If True, x has to be an array of monotonically increasing
              values.
          kwargs: dictionary
              Additional keyword passed to scipy's interpolator.
          **coords_kwarg : {dim: coordinate, ...}, optional
              The keyword arguments form of ``coords``.
              One of coords or coords_kwargs must be provided.
  
          Returns
          -------
          interpolated: xr.DataArray
              New dataarray on the new coordinates.
  
          Notes
          -----
          scipy is required.
