A new three‐dimensional model for stratospheric chemistry studies is described. The model, a spectral general circulation model, is developed from the model used at the European Centre for Medium‐range Weather Forecasts. Schemes to describe atmospheric chemistry and photochemistry as well as advection of trace gases have been implemented. In this study a perturbed period in January 1987 is studied. The model performs well. An interesting feature, similar to the Noxon cliff, is reproduced in which the NO 2 column is reduced significantly in high latitudes. In this calculation the cliff is produced by gas phase conversion of NO 2 to N 2 O 5 .
