Chlorine activation of the lower stratosphere at mid-latitudes: Impact on the ozone layer

Resumo

The algorithm and the results of calculations of the dynamics of stratospheric ozone depletion at mid-latitudes are reported. The data were obtained based on numerical simulations of the dynamics of gas-phase and heterophase reactions involving Junge layer particles. The contribution of heterophase reactions to the ozone layer depletion is evaluated, and the necessity of considering them in predicting the recovery of the ozone layer in the XXI century is justified.
