THE 3RD WORKSHOPS ENVIRONMENTAL-IMPACT ASSESSMENT MODEL INTERCOMPARISON EXERCISE

Twelve European modelling teams calculated the impact of a 600 MW powe r plant, using one of their national regulatory transport and dispersi on models. They were asked to report the model results in a uniform wa y and to provide detailed information on the meteorological data and o n the model used. Three modelling teams, from Greece, Germany and Belg ium, 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.
