Destruction of Atmospheric Ozone in Ox, HOx, NOx, ClOx, BrOx, and IOx Catalytic Cycles

Data on the relative contribution of the O-x, HOx, NOx, ClOx, BrOx, and IOx catalytic cycles to atmospheric ozone destruction are given for June and January 2000 at a latitude of 50 degrees N in the height range of 0-50 km. The height profiles of the components of the above families have been calculated using the SOCRATES two-dimensional interactive model and the one-dimensional photochemical model developed at the Tal'rose Institute of Energy Problems of Chemical Physics, Russian Academy of Sciences. The initial data for the calculations are taken to be the atmospheric content of greenhouse gases according to the Intergovernmental Panel on Climate Change RCP 4.5 scenario for 2000. The ozone destruction rate is calculated using an algorithm proposed earlier by the author to determine the rate of the limiting stage of the catalytic cycle.
