ABSTRACT

Algorithm for calculation of the chain length and rate of stratospheric ozone depletion in O_x, HO_x, NO_x, ClO_x and BrO_x cycles has been developed. The most important new element in the theory of stratospheric chain processes is the correct determination the propagation rate, taking into account all reactions involved rather than a single reaction, which has the lowest rate, as it was usually done before. The role of null chain processes in the cycles has been considered and shown that these processes play a decisive role in formation of families of the odd oxygen, nitrogen, chlorine and bromine in the daytime while at night they play no role. Using two-dimensional model Socrates, and algorithm developed correct rate of ozone depletion and chain length in the cycles above for model conditions of June 2020 at 50^。N have been calculated.
