DatasetRolling.reduce(func, keep_attrs=None, **kwargs)[source]#

Reduce the items in this group by applying func along some dimension(s).

  • func (callable()) – Function which can be called in the form func(x, **kwargs) to return the result of collapsing an np.ndarray over an the rolling dimension.

  • keep_attrs (bool, default: None) – If True, the attributes (attrs) will be copied from the original object to the new one. If False, the new object will be returned without attributes. If None uses the global default.

  • **kwargs (dict) – Additional keyword arguments passed on to func.


reduced (DataArray) – Array with summarized data.
