Abstract
Regional-scale tracer experiments are needed to validate atmospheric dispersion aspects of air pollution models. The capability of a new system, using perfluorocarbon tracers (PFTs), for long-range dispersion experiments at reasonable cost, was demonstrated in two experiments. Two PFTs were released simultaneously with SF6 and two heavy methanes. The PFT system uses automatic sequential samplers and provides rapid, inexpensive analyses down to .002 ppt. PFT concentrations were measured 600 km away, up to three days after release. Performance of the PFT system was excellent and a very consistent set of tracer data was obtained.
