Two-dimensional simulation of seasonal and latitudinal variations in the total atmospheric ozone content with the use oflarge-scale transport parameters from an atmospheric general circulation model

Two two-dimensional zonal average photochemical models of the lower and middle atmosphere are used to study the effect of dynamic parameters on the spatiotemporal distribution of atmospheric ozone. The results of model calculations obtained in a purely two-dimensional representation and with the use of three- dimensional calculations based on a general circulation model are compared to measurement results. The results of the three-dimensional calculations are used as the input parameters for the two-dimensional zonal average photochemical models, which allows one to use the advantages of a three-dimensional representation of the large-scale atmospheric transport in simulating photochemical processes with the aid of two-dimensional models. The use of the three-dimensional fields of the MACCM2 general circulation model allows one to improve the agreement between the calculated and measured (with the aid of the TOMS instrument) seasonal and latitudinal fields of the total ozone content for the SUNY-SPB and GGO zonal average models.
