Abstract

Aircraft emissions can affect the tropopause region through their impact on chemical and radiative processes. They may thus play a peculiar role for an- thropogenically induced modifications of the Earth's climate. The effect of subsonic aircraft emissions on the chemical system of the tropopause region is investigated using a special version of the European Air Pollution Di- spersion Model (EURAD). Simulations have been carried out for the North Atlantic flight corridor. The role of the composition of the background at- mosphere is analysed in particular. The results show a clear dependence of ozone changes as induc
