# cf.Field.cell_area¶

Field.cell_area(radius='earth', great_circle=False, set=False, insert=False, force=False)[source]

Return a field containing horizontal cell areas.

New in version 1.0.

Parameters

Specify the radius used for calculating the areas of cells defined in spherical polar coordinates. The radius is that which would be returned by this call of the field construct’s radius method: f.radius(radius). See the cf.Field.radius for details.

By default radius is 'earth' which means that if and only if the radius can not found from the datums of any coordinate reference constucts, then the default radius taken as 6371229 metres.

great_circle: bool, optional

If True then allow, if required, the derivation of i) area weights from polygon geometry cells by assuming that each cell part is a spherical polygon composed of great circle segments; and ii) and the derivation of line-length weights from line geometry cells by assuming that each line part is composed of great circle segments.

New in version 3.2.0.

insert: deprecated at version 3.0.0

Returns
Field

A field construct containing the horizontal cell areas.

Examples:

>>> a = f.cell_area()
