Abstract

The LLL one-dimensional stratospheric model was used to examine the effect of variations of reaction rate coefficients on computed concentrations of stratospheric ozone, and in particular, on the magnitude of the effect of the perturbation in the ozone column resulting from the injection of oxides of nitrogen into the stratosphere. Five models were generated by varying sets of reaction rate coefficients within their estimated uncertainties. Some conclusions that can be drawn from this study include: uncertainties in chemical rate coefficients can produce major uncertainties in ozone perturbations resulting from NO//x injections. Models predicting very different responses of ozone to NO//x injections can all be consistent with the observed stratospheric concentrations of minor species. Therefore, there are clear limitations on the utility of stratospheric observations in estimating the reliability of models as predictive tools.
