In the absence of heterogeneous processes, distributions of NO y , HNO 3 , Cl x and HCl in the polar winter stratosphere should be determined by transport. A model simulating distributions of these species in the arctic for January and February 1989 is developed using observed fields of potential vorticity and potential temperature. Comparison of model results with column measurements from the DC‐8 indicates conversion of NO x to HNO 3 , condensation of HNO 3 , conversion of HCl to ClNO 3 , and conversion of HCl plus ClNO 3 to an unmeasured species. Heterogeneous processes strongly affect abundances of NO y and Cl x species in the winter arctic stratosphere.
