Conclusions
The main objectives of this study was to carry out the link between the meteorological model RAMS and the Lagrangian particles model SPRAY in order to simulate the transport and diffusion processes and to verify its ability to describe the dispersion of a tracer emitted during the TRACT experiment. According to the results here presented, it is possible to state that such goals were reached. In particular, the comparisons of modelled and observed meteorological variables show that RAMS simulates very well the TRACT experiment. The model system correctly reproduces the general behaviour of the contaminant plume, the temporal and spatial distribution of the concentration and the location of the concentration maximum. It is also shown that the connection between RAMS and SPRAY, through MIRS, is fully operative.
