The Third Workshop's environmental impact assessment model intercomparison exercise
Twelve European modelling teams calculated the impact of a 600 MW power plant, using one of their national regulatory transport and dispersion models. They were asked to report the model results in a uniform way and to provide detailed information on the meteorological data and on the model used. Three modelling teams, from Greece, Germany and Belgium, used the same meteorological dataset. The reported parameters of the calculated impact are generally within a factor of 10. Taking into account the differences in the meteorological data used, about 50% of the differences in the reported averages can be explained.
