Results are described for a self-consistent one-dimensional coupled flow calculation for O/sub x/, NO/sub x/, HO/sub x/, ClX, H/sub 2/O, H/sub 2/, CH/sub 4/, H/sub 2/O/sub 2/, and N/sub 2/O densities between 10 and 120 km. Results agree well with observations for the normal mid-latitude atmosphere over this altitude range. ClX, NO/sub x/, and H/sub 2/O were varied independently in the model. The effect of depletion of ozone by ClX is to remove ozone preferentially above 30 km and to lower the altitude of maximum ozone density. This leads to enhanced solar heating of the lower stratosphere and tropopause and suggests the possibility of an increased flux of water into the stratosphere. Increasing water vapor in the stratosphere greatly enhances the rate of destruction of O/sub 3/ by ClX and also causes an increase in the rate of destruction of O/sub 3/ in the NO/sub x/-perturbed atmosphere.
