xarray.Dataset.ffill

Dataset.ffill(dim, limit=None)[source]

Fill NaN values by propogating values forward

Requires bottleneck.

Parameters
  • dim (Hashable) – 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.

Returns
