xarray.core.rolling.DatasetRolling

class xarray.core.rolling.DatasetRolling(obj, windows, min_periods=None, center=False)

__init__(obj, windows, min_periods=None, center=False)

Moving window object for Dataset. You should use Dataset.rolling() method to construct this object instead of the class constructor.

Parameters:

obj : Dataset

Object to window.

windows : A mapping from a dimension name to window size

dim : str

Name of the dimension to create the rolling iterator along (e.g., time).

window : int

Size of the moving window.

min_periods : int, default None

Minimum number of observations in window required to have a value (otherwise result is NA). The default, None, is equivalent to setting min_periods equal to the size of the window.

center : boolean, default False

Set the labels at the center of the window.

Returns:

rolling : type of input argument
