Meteorological parameters strongly affect atmospheric dispersion which makes developing a simulation to get a prediction of the odour impact significant to understand the effect of the same sources located in different sites. Each location has peculiarities depending on orography, distance from the sea and mainly wind speed and direction. This study evaluates the impact of two ideal sources, one areal on the ground and one point source at altitude, having the same odour flow.Generally, odour dispersion is affected by wind speed near the emission, so higher concentration are expected from the ground based source. The findings consistently demonstrate that this source yields the most significant odour impact, while wind speed at altitude primarily influences dispersion from the point source. Despite the areal ground-level source has a greater impact at all locations, the ratio of the mean of the two sources mean simulated impact has a linear dependence with the distance from the emission point. |
