The UK Chemistry and Aerosols (UKCA) model the active role of ozone in a changing climate (WMO, 2007; is a new aerosol-chemistry model coupled to the Met Office IPCC, 2007). Presently there are only a few CCMs available Unified Model capable of simulating composition and cli- that cover both tropospheric and stratospheric ozone chem- mate from the troposphere to the mesosphere.
