Abstract: Two Gaussian short-range atmospheric dispersion models, TSTEP and REM-3, have been validated with the Kincaid dataset of the Model Validation Kit. TSTEP and REM-3 show high scatter compared to the observations. Both models have the tendency to underestimate lower concentratrations and to overestimate higher concentrations, but, within a factor of five, many predictions are in agreement with the observations. A comparison of TSTEP with REM-3 shows that the models are in good agreement with each other, in particular for low concentrations. Both models are sensitive to the choice of the (effective) release height.

Keywords: Kincaid dataset; model intercomparison; model validation; model validation kit; operational short-range dispersion model.
