EnglishThe reliability of models of dispersion of pollutants in the atmosphere is a key element in the choice of instruments used for environmental assessments. The objective of this study is to compare the results of two mathematical models (CALPUFF and ADMS-Urban) applied in the urban area of Ravenna. The pollutants considered are PM10 and NO2. The results show that CALPUFF simulates higher concentration values than ADMS-Urban, in particular near emission sources and in conditions of wind calm. The results were validated by statistical (arithmetic mean, bias, FB, correlation coefficient, FA2, NMSE, IOA) and diagnostic analysis. The analysis suggests that the different response of the two models is primarily influenced by the different influence that the wind speed has in the mathematical treatment of the model.
