Abstract
A concentration fluctuation model is presented which is suitable to simulate the dispersion of odorous substances in the atmosphere. This tool has been combined with a meteorological model for the planetary boundary layer in order to provide the relevant meteorological variables wind and turbulence. The model system has been validated against field observations and the results show a good agreement in the spatial distribution of mean concentration as well as for concentration variance and other statistical measures. The validated model was used to simulate the long-term dispersion of odors for one complete year. The calculated time series has been analysed with respect to threshold crossing rates and annual odor hours. A comparison of the results of different methods for calculating the odor hours demonstrates the deficiencies of simple approaches.
