Time-dependent release scenarios for carbon dioxide and chlorofluoromethanes (CF/sub 2/Cl/sub 2/, CFCl/sub 3/) are assumed. The combined effects on stratospheric ozone and temperature are examined with a time-dependent radiative-convective-photo-chemical model. A steady-state version of the model is used to determine surface temperature effects and to establish asymptotic levels. Results indicate the following: (1) the total ozone time history is significantly different from that due to the chlorofluoromethanes alone; (2) a local ozone minimum occurs in the upper stratosphere about 45 years from the present with a subsequent ozone increase, then decline; and (3) steady-state solutions indicate that tropospheric temperature and water vapor increases, associated with increased infrared opacity, cause significant changes in tropospheric ozone levels for 2 x CO/sub 2/ and 4 x CO/sub 2/ with and without the addition of chlorofluoromethanes.
