A two-dimensional atmospheric model has been developed to take into account latitudinal and seasonal effects in the calculation of atmospheric constituent profiles. The model includes 30 active chemical species and all chemical reactions and reactions rates applicable to them for the domain from pole to pole and 0 to 55 km height; mean meridional circulation is parameterized using the advective circulation field of Murgatroyd and Singleton (1961), while eddy diffusion parameterization is basically that of Luther (1974) and spatial derivatives for transport are approximated by a second-order finite difference representation. Time-dependent integration of the model results in latitudinal variations of the N2O volume mixing ratio, CFCl3, CF2Cl2 and CH4, column ozone and HNO3 in agreement with available measurements, whereas the agreement between calculated and measured HCl and ClO profiles is found to be no better than that obtained with one-dimensional models.
