Abstract: SAFE_AIR is a code simulating the transport and diffusion of airborne pollutants. This code is based on the advection of Gaussian segments and puffs driven by a 3-D wind field produced by a diagnostic model, able to deal with both non-stationary and inhomogeneous conditions. SAFE_AIR is an evolution of the AVACTA II code, ||recommended|| by the US EPA (United States Environmental Protection Agency). We have recently revised the simulation of the plume rise phenomenon. We have evaluated this last version of the SAFE_AIR code against the Kincaid dataset; here we present the results obtained using both the plume rise formulae recommended by Briggs and the plume rise Moore model; the interaction between the rising of the plume and the top of the mixed layer is also taken into account.

Keywords: air pollution; Kincaid dataset; local-scale; stack source.
