# xarray.core.resample.DatasetResample.nearest

`DatasetResample.``nearest`(tolerance=None)

  Take new values from nearest original coordinate to up-sampled frequency coordinates.

  Parameters: | tolerance (optional) – Maximum distance between original and new labels to limit the up-sampling method. Up-sampled data with indices that satisfy the equation `abs(index[indexer] - target) <= tolerance` are filled by new values. Data with indices that are outside the given tolerance are filled with `NaN` s
