xarray.Dataset.interp

Dataset.interp(coords=None, method='linear', assume_sorted=False, kwargs=None, **coords_kwargs)

Multidimensional interpolation of Dataset.

Parameters
  • coords (dict, optional) – Mapping from dimension names to the new coordinates. New coordinate can be a scalar, array-like or DataArray. If DataArrays are passed as new coordinates, their dimensions are used for the broadcasting. Missing values are skipped.

  • method (str, optional) – {“linear”, “nearest”} for multidimensional array, {“linear”, “nearest”, “zero”, “slinear”, “quadratic”, “cubic”} for 1-dimensional array. “linear” is used by default.

  • assume_sorted (bool, optional) – If False, values of coordinates that are interpolated over can be in any order and they are sorted first. If True, interpolated coordinates are assumed to be an array of monotonically increasing values.

  • kwargs (dict, optional) – Additional keyword arguments passed to scipy’s interpolator. Valid options and their behavior depend on if 1-dimensional or multi-dimensional interpolation is used.

  • **coords_kwargs ({dim: coordinate, ...}, optional) – The keyword arguments form of coords. One of coords or coords_kwargs must be provided.

Returns

interpolated – New dataset on the new coordinates.

Return type

Dataset

Notes

scipy is required.
