# cf.Field.source¶

Field.source

The source CF property.

The method of production of the original data. If it was model-generated, source should name the model and its version, as specifically as could be useful. If it is observational, source should characterize it (for example, 'surface observation' or 'radiosonde'). See http://cfconventions.org/latest.html for details.

Examples:

>>> f.source = 'radiosonde'
>>> f.source

>>> f.set_property('source', 'surface observation')
