Validation of odour dispersion models - An intercomparison of models by odour measurements

An intercomparison of models of odour dispersion models by odour measurements is presented. Odour measurements were carried out in the vicinity of an oil mill in 2000 and 2001. The agreement of measured and calculated odour frequencies determined by plume measurements differs depending on the evaluation concept. The results of the simulations for the grid measurements in ambient air by panels agree well by application of the models TA Luft factor 10, LASAT factor 4 and MEPOD. The model intercomparison points out the importance to establish explicit rules for the validation of odour dispersion models when laying down guidelines.
