  • SNAP model results using different meteorological inputs compared with experimental data from the European Tracer Experiment : A contribution to modelling on regional and global scales


This paper describes the European Tracer Experiment (ETEX) which is jointly organized by the CEC, IAEA and WMO. It was established to evaluate the validity of long range transport models for real time application in emergency management and to assemble a database which will allow the evaluation of long range atmospheric dispersion models in general. The first experiment took place in October 1994. A perfluorocarbon (PFC) tracer was released into the atmosphere for 12 hours in Monterfil, Brittany, and air samples were taken at 168 stations in 17 European countries and subsequently analysed for tracer concentration a the Environment Institute, Ispra. At each site 3 hour samples were taken for a total length of 72 hours after the release. Routine meteorological and additional observations at ground and upper air were gathered for a 7 day period around the release time.
