TRANSALP consisted of three tracer field experiments carried out in the Ticino area of southern Switzerland in the years 1989, 1990 and 1991. The experiments were designed to study the trace gases transport and diffusion over the very complex Alpine topography. The results and knowledge gained from each experiment were used for the design of the next experiment and to improve the logistics. The experiments contributed to the understanding of the flow and dispersion characteristics in the very complex terrain. Specifically, they gave evidence, under particular meteorological conditions, of the occurrence of a transalpine air constituents exchange, both in north-south (N-S) and south-north (S-N) directions. Data collected were stored in a data bank, made available to those interested in evaluating atmospheric dispersion models.
