Abstract
The use of Chlorofluorocarbons (CFCs) in ocean modelling is evaluated for different kinds of models and configurations. These models range from an idealized basin model to a global ocean model. In the later case, the CFC-11 concentrations in the global ocean model are compared to observations when using three different sub-grid-scale mixing parameterizations: a lateral/vertical scheme; an isopycnal scheme; and the Gent and McWilliams scheme. The Gent and McWilliams scheme improves the CFC-11 distributions when compared to both of the other schemes. The main improvement comes from a reduction of CFC uptake in the Southern Ocean.
