Abstract

Most previous attempts to estimate the effects of atmospheric contaminants on stratospheric ozone have involved one-dimensional models of the troposphere and stratosphere. Estimates of the distribution of HCl and ClO with height have, however, failed to match the measured concentration profiles1. Hence, there has been much interest in the development of two-dimensional atmospheric models which, by including variations with latitude and seasonal effects, might remove these discrepancies. We have developed such a two-dimensional model which incorporates the refinements of the most advanced one-dimensional models; we now report that, contrary to expectation, the calculated profiles of HCl and ClO are insignificantly different from those of comparable one-dimensional models.
