Radiative forcing due to changes in ozone: a comparison of different codes
The radiative forcing due to changes in ozone in the troposphere and stratosphere is calculated using a number of different radiative transfer codes and the results are compared. The calculations use a tightly specified set of input parameters. The 14 µm band of ozone is shown to make a significant contribution to the forcing for changes in stratospheric ozone, although, because of line overlap, it is of less importance for tropospheric ozone changes. The main cause of the spread in results is differenees in the solar forcings; these differences are believed to reflect simplifications used in parameterizations rather than the actual uncertainty in modelling solar irradiances.
