Effect of the JUNGE Layer on Chain Processes in the Chapman Cycle

Results of calculations of the effect of Junge layer particles on the Chapman cycle chain length in the lower stratosphere are cited. The calculation data correspond to conditions of 50°n.l. within the 10–25 km height range in June, 1995. Calculations were performed using the SOCRATES interactive two-dimensional model and the ChemWG zero-dimensional model for dynamics of gas and heterophase chemical reactions. As initial data for the calculations, forecasts of atmospheric greenhouse gases content by Intergovernmental Panel on Climate Change RCP 4.5 for 1995 were taken. The paper discusses mechanisms of the effect Junge layer particles produce on chain processes in the Chapman cycle in the lower stratosphere.
