Short summary
Satellite observations are used to constrain areas with large backscatter values areas inside the polar vortex. Surface area is derived from these observations and used in heterogeneous modeling. Satellite gas species observations show a decrease in HCl downwind of areas with large surface area density indicating heterogeneous processing inside these areas. This decrease can only be simulated if a realistic surface area is assumed demonstrating the importance of polar stratospheric cloud.
