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
'radiosonde'
>>> del f.source
>>> f.setprop('source', 'surface observation')
>>> f.getprop('source')
'surface observation'
>>> f.delprop('source')
