cf.DomainAncillary.add_offset

DomainAncillary.add_offset()

The add_offset CF property.

If present then this number is subtracted from the data prior to it being written to a file. If both scale_factor and add_offset properties are present, the offset is subtracted before the data are scaled. See http://cfconventions.org/latest.html for details.

Examples:

>>> f.add_offset = -4.0
>>> f.add_offset
-4.0
>>> del f.add_offset

>>> f.setprop('add_offset', 10.5)
>>> f.getprop('add_offset')
10.5
>>> f.delprop('add_offset')
