Abstract: | The possibility of significant autocatalytic ozone production in the middle atmosphere has been demonstrated by Toumi et al. A detailed framework including five processes previously not considered is presented here. When these processes are included, particularly wavelength-dependent vibrational distributions of O2, calculated ozone enhancements are less than 10% in the upper stratosphere and lower mesosphere. The vibrational distributions and the rate of vibrational quenching are identified as key issues which need to be addressed by experiments. |
