Abstract

An intercomparison of different classical models for the evaluation of air pollutant diffusion in steady conditions on flat terrain - namely ISC3, DIMULA, HPDM, KAPPAG - has been performed with emission and meteorological data relative to the industrial site of Porto Marghera (Northern Italy). Two of the models - ISC and DIMULA - have been also checked against the benchmark data collected within the Kincaid experiments, and their performance has been evaluated subjectively - in term of maximum ground concentration and its distance from source - and objectively by a series of statistical indices. The whole exercise has been performed with a user perspective, in order to evaluate reliability and expected difference between the different models in operational use. 1.
