Transborder transport of air pollutants

Abstract

A simple trajectory model is used in order to estimate how the emission of SO2 in one country influences the level of background pollution in each of the participating countries. The calculations include also the influences due to emission within countries not participating in the LRTAP PROJECT. The transport budget depends on the choice of wind when computing the trajectories. Model estimates are therefore presented for calculations based on various winds between the surface layer and the 850 mb level.
