Abstract

The Scientific Basis of NO% Protocols and the EU Ozone Strategy Invited contribution from EMEP David Simpson EMEPMSC-W, The Norwegian Meteorological Institute, P.B. 43, N-0313 Oslo, Norway The first Protocol for the reduction of emissions aimed at preventing the long- range transport of harmful substances was the UN-ECE sulfur Protocol, which was signed in Helsinki in 1985. This Protocol was the result of years of research which had demonstrated both the harmful effects of sulfur emissions, and the international character of the problem. Long-range transport models (Eliassen, 1978, Eliassen and Saltbones, 1983) played a key role, not only in demonstrating that sulfur could indeed be transported many thousands of km from the source (a disputed idea in this early work), but also in calculating country-to-country source-receptor matrices. The sulfur model
