A comparison between the dispersion of odour modelled by AERMOD and CALPUFF was here presented. In order to obtain results, an ideal case, considering both a point source and an are source, was run in different meteorological conditions belonging to a standard year.
The results show a good agreement between the two models except for stable atmospheric condition for which the AERMOD plume are longer and more concentrated, thus the only way to discriminate results or feedback from citizens of the considered area.
