Decisions in the management and control of atmospheric pollution are increasingly based on results of atmospheric dispersion models, which should therefore be extensively verified and validated in a comprehensive programme of model development and application. The use of perfluorocarbon (PFC) tracers has potential for validation of the mesoscale and long range models that are of particular importance in the transfrontier problems of the European Community. This paper presents an analysis of two in-field campaigns carried out under the TRANSALP project (TRACT-EUROTRACT). The experimental tracer concentration values are compared with those calculated by means of a particle-in-cell model, coupled with a diagnostic wind-field model. The planning of a European Tracer Experiment (ETEX), aimed at qualifying the long range atmospheric transport models over episodes in the range of a few thousand kilometres, is also reported.
