cf.CellMeasure

class cf.CellMeasure(properties={}, data=None, attributes={})

Bases: cf.variable.Variable

A CF cell measure construct containing information that is needed about the size, shape or location of the field’s cells.

It is a variable which contains a data array and metadata comprising properties to describe the physical nature of the data.

The name of spatial measure being represented is stored in the measure attribute.

Initialization

Parameters :

properties : dict, optional

Initialize a new instance with CF properties from the dictionary’s key/value pairs. Values are deep copied.

data : cf.Data, optional

Provide the new instance with an N-dimensional data array. The array is deep copied.

attributes : dict, optional

Provide the new instance with attributes from the dictionary’s key/value pairs. Values are deep copied.
