“…Concerning emissions from area sources, the emissive parameter commonly referenced is the Specific Odor Emission Rate (SOER), i.e., the emission flow per square meter of the source. In addition, for area sources, as suggested by recent investigations [50,51], the odor emission rate was considered constant, as no hourly profile information is available, and it is not affected by wind velocity.…”

Dispersion modeling is a useful tool for reproducing the spatial–temporal distribution of pollutants emitted by industrial sites, particularly in the environmental odor field. One widely used tool, accepted by regulatory agencies for environmental impact assessments, is the CALPUFF model, which requires a large number of input variables, including meteorological and orographical variables. The reliability of model results depends on the accuracy of these input variables. The present research aims to discuss a comparative study of odor dispersion modeling by initializing the CALMET meteorological processor with different input data: surface and upper air observational meteorological data, 3D prognostic data, and a blend of prognostic and measured data. Two distinct sources (a point and an area source) and two different simulation domains in Cuba and Italy are considered. The analysis of results is based on odor impact criteria enforced in some Italian regions by computing the 98th percentile of odor peak concentrations on an annual basis. For the area source, simulation results reveal that the ‘OBS’ and ‘HYBRID’ modes are largely comparable, whereas prognostic data tend to underestimate the odor concentrations, likely due to a reduced percentage of wind calms. For point sources, different input meteorological settings provide comparable results, with no significant differences.

“…For point sources, such as stacks and chimneys, emission rates can be measured rapidly. On the other hand, when dealing with non-point sources, the estimation of the emission rate is a particularly challenging task due to the difficulties of direct sampling and the possible influence of different external variables, such as temperature and wind speed, on the emission rate of this kind of source (Invernizzi et al, 2019;Tagliaferri et al, 2021). Also, management and logistical practices may influence the emission from aerated basins and storage tanks (Invernizzi et al, 2020;Invernizzi and Sironi, 2021).…”
