High Resolution, Long-Period Modelling of Photochemical Oxidants over Europe

Concentrations of surface ozone over Europe currently exceeds the critical levels over which damage to vegetation and health may occur in many locations. This is true also in northern Europe and over Sweden regarding critical levels for vegetation and also occasionally, during summer in southern Sweden, regarding critical levels for human health. Optimising measures to reduce these exeedances, both nationally and internationally, requires a better understanding of the importance of various types of precursor emissions and processes influencing the distribution of photochemical oxidants.
