Abstract

ATMOSPHERIC TRACERS ARE A VERSATILE TOOL THAT CAN BE USED IN CONJUNCTION WITH BASIC METEOROLOGICAL INVESTIGATIONS AND MODELS TO GAIN A BETTER UNDERSTANDING OF THE DYNAMICAL BEHAVIOUR OF ATMOSPHERIC POLLUTANTS ON BOTH THE LOCAL AND REGIONAL SCALES. THE TRACER ACTIVITY WAS INITIATED AT ISPRA ABOUT TEN YEARS AGO, WITH THE AIM OF PROVIDING AN EXPERIMENTAL SUPPORT TO THE RESEARCH ACTIVITY CARRIED OUT IN THE FIELD OF AIR POLLUTION MODELLING. AT THAT TIME THE AREA OF INTEREST WAS MAINLY RELATED TO THE ATMOSPHERIC DISPERSION ON A LOCAL SCALE OF POLLUTANTS RELEASED FROM STACKS OF POWER STATIONS, THEREFORE A TECHNIQUE USING SF AS A TRACER WAS IMPLEMENTED. IN THE LAST FEW YEARS SOME EFFORTS HAVE BEEN DEVOTED ALSO TO THE DETERMINATION OF THE ATMOSPHERIC DISPERSION PARAMETERS IN THE MESOSCALE AND IN THE REGIONAL SCALE. DUE TO THE LIMITATIONS IN THE USE OF SF(6) OVER THESE DISTANCES, A NEW TECHNIQUE UTILISING PERFLUOROCARBONS { C(7)F(14) AND C(8)F(16) } AS TRACERS HAS BEEN IMPLEMENTED AND POSITIVELY TESTED IN THE FIELD, EVEN THOUGH LIMITED UNTIL NOW TO A FEW SHORT RANGE EXPERIMENTS. THE PURPOSE OF THIS PRESENTATION IS TO DESCRIBE THE TRACER TECHNOLOGY DEVELOPMENTS AT THE JRC - ISPRA INCLUDING THE MAIN RESULTS OBTAINED IN DIFFERENT FIELD STUDIES.
