Abstract

Perturbing the stratospheric composition affects the stratospheric temperature profile via the radiation balance. Changes in temperature affect chemical reaction rates, which in turn feed back on stratospheric composition. The effect of temperature feedback on ozone concentration has been investigated for three types of perturbations: (1) stratospheric injection of NO//x, (2) release of fluorocarbons, and (3) doubling CO//2. Temperature feedback had approximately a 105 restoring effect on ozone for small ozone reductions because of either stratospheric NO//x injection or release of fluorocarbons. Doubling CO//2 concentrations increased total ozone by 2. 95. Calculations of ozone reduction including temperature feedback were as much as less than fixed temperature calculations using the U. S. Standard Atmosphere temperature profile.
