Abstract
The RAMS-CALMET-CALPUFF modelling system has been used to simulate the odorous impacts from a paper-mill in an urban area located several kilometres away in a coastal mountainous area.
Over the last years, episodes of citizens complaints due to malodours have been registered, with a potential origin in several pollution sources located inside and outside the city. A selection of episodes under anticyclonic conditions, with poor ventilation in general and continuous changes of stability and wind during the day, has been simulated. It is intended to confirm or not the possibility that the odorous impact of the paper-mill is behind the citizens’ complaints and the odour concentrations registered during a series of field olfactometry campaigns.
The hourly outputs of the meteorological simulations have been validated against data from surface stations, a wind profiler radar and nearby radio-soundings. The simulations results show that the model is able to simulate in a quasi-synchronous manner the odour impacts with the complaints and the experimental odour measurements in the urban area.
