Abstract

Numerical data are presented on the chain length of the so-called zero oxygen cycle, i.e. such a cycle in which ozone destruction does not occur as in purely catalytic cycles. The data correspond to the conditions of June 2000 at latitude 50 N in the altitude range of 15–55 km. Calculations were performed using the interactive two-dimensional SOCRATES model. Forecasts of atmospheric greenhouse gas content of the Intergovernmental Panel on Climate Change RCP 4.5 for the year 2000 were used as initial data for calculations. Calculations of the chain length of zero cycles were carried out using the algorithm proposed earlier by the author for determining the speed of the limiting stage of the catalytic cycle.
