# xarray.Dataset.ffill¶

Dataset.ffill(dim, limit=None)

Fill NaN values by propogating values forward

Requires bottleneck.

Parameters: dim : str Specifies the dimension along which to propagate values when filling. limit : int, default None The maximum number of consecutive NaN values to forward fill. In other words, if there is a gap with more than this number of consecutive NaNs, it will only be partially filled. Must be greater than 0 or None for no limit. Dataset
