THREE-DIMENSIONAL DYNAMICAL-CHEMICAL MODEL OF ATMOSPHERIC OZONE.

Abstract

A three-year integration of a global three-dimensional model including dynamics and simple photochemistry is used to predict ozone. Distributions of NO//2 and odd hydrogen deduced by J. C. McConnell and M. B. McElroy are used to incorporate in a simple way the chemical effect of these species. Good agreement with observation is obtained for stratospheric motion patterns, meridional circulations, ozone density as a function of height and latitude, eddy transports of ozone, surface destruction of ozone, and correlations of ozone with other variables. The principal deficiency of the model is an underprediction of the spring ozone concentration in high latitudes in the lower stratosphere.
