cf.AuxiliaryCoordinate

class cf.AuxiliaryCoordinate(properties={}, attributes={}, data=None, bounds=None, copy=True)

Bases: cf.coordinate.Coordinate

A CF auxiliary coordinate construct.

Attributes

Attribute	Type	Description
climatology	bool	Whether or not the bounds are intervals of climatological time. Presumed to be False if unset.

Initialization

Parameters :

properties : dict, optional

Initialize a new instance with CF properties from a dictionary’s key/value pairs.

attributes : dict, optional

Provide the new instance with attributes from a dictionary’s key/value pairs.

data : cf.Data, optional

Provide the new instance with an N-dimensional data array.

bounds : cf.Data or cf.CoordinateBounds, optional

Provide the new instance with cell bounds.

copy : bool, optional

If False then do not copy arguments prior to initialization. By default arguments are deep copied.
