The main objectives of the SMEDIS project is to develop a methodology for the evaluation of atmospheric dispersion models used in the study of accidental releases of explosive or toxic materials. This evaluation is composed of a scientific assessment of each model capability, followed by a validation by comparison with experimental data.

This paper describes more specifically the database constructed and the validation performed by the participants involved in the project. Preliminary results indicate that the restriction to arc-wise concentration lead to an optimistic view of model performance when complex effects are present and that, in general, statistical performance is better for more sophisticated model.
