Numerous numerical dispersion models have been developed to predict long range transport of hazardous air pollution in connection with accidental releases. When developing and evaluating such a model, it is important to detect uncertainties connected to insufficient characterization of the accidental release, the meteorological input data, errors in the formulation of the Numerical Weather Prediction (NWP) model, and errors in the formulation of the dispersion model.
