One such pollutant is inorganic chlorine , Cl y , which has reactive forms implicated in rapid ozone destruction. As illustrated in Figure 2 for two regions of the stratosphere, there is a clear correlation between Cl y and the mean age across models. Moreover, the uncertainty in both Cl y and mean age is more than a factor of 2 at these locations. Such large Cl y variations will produce significant uncertainties in simulations of ozone chemistry. These results indicate that there is room for improvement in models that are used to predict the impact of industrial gases on the ozone layer, and inaccuracies in transport are a major source of the error.
Further research is critical to better understand and simulate atmospheric transport.
