On 23 October and 14 November 1994 two releases of perfluorocarbon atmospheric tracer (PFC) were made in Europe, as a part of the project ETEX, aimed at validating atmospheric transport models when used in real time, as is necessary for emergency management purposes. Air samples were taken for 72 hours at 170 sampling stations in Europe, and upper air samples were taken by three aircraft following each release. The PFC cloud evolution forecast by 28 models from 20 countries will be compared with the experimental results. While the analytical campaign is only at its beginning, the tracer has been successfully measured at sampling sites up to 1500 km from the source, suggesting that the PFC concentration can be measured in the entire test field.
