Abstract

Modeling of heterogeneous reactions related to the stratospheric ozone depletion in the polar region is explained. The reactions are incorporated into the chemical transport model (CTM) of the Center for Climate System Research, University of Tokyo / National Institute for Environmental Studies (CCSR/NIES) . Thirteen heterogeneous reactions on liquid binary sulphate aerosols (LBA) , supercooled ternary solutions (STS) , nitric acid tri-hydrate (NAT) , and ice particles were taken into account. The CTM was applied to calculate the ozone destruction in the Arctic in 1995, 1996, and 1997, when a large amount of ozone destruction occurred. The calculated results were analyzed for studying the effects of bromine species on the ozone destruction. The results showed that the BrO-ClO catalytic cycle works efficiently in the stable Arctic polar vortex in the 1997 spring owing to the long-time coexistence of high concentrations of BrO and ClO. The situation is similar to the ozone destruction in the Antarctic in October and November.
