Abstract

The pollutant transport associated with the TRANSALP experimental tracer release, conducted in South Switzerland on 29 September 1990, is modelled. The region in which the experiment took place has a complex topographical structure. The TRANSALP release was made at a critical site of the terrain, at the beginning and near the base of a major valley (Leventina Valley), while a dense network of ground tracer samplers was installed along the valley's axis, as well as at several significant surrounding points. The simulation is based on the DEMOKRITOS transport code system, consisting of the topography simulator DELTA, the mesoscale atmospheric model ADREA and the Lagrangian dispersion model DIPCOT-II. The predicted concentration patterns are compared with the observations, and show that the major dispersion features are well reproduced.
