Multi-Model Versus EPS-Based Ensemble Atmospheric Dispersion Simulations: A Quantitative Assessment on the ETEX-1 Tracer Experiment Case
Several techniques have been developed over the last decade for the ensemble treatment of atmospheric dispersion model predictions. Among them two have received most of the attention, the multi-model and the Ensemble Prediction System (EPS) modeling. The multi-model approach relies on model simulations produced by different atmospheric dispersion models using meteorological data from potentially different weather prediction systems. The EPS-based ensemble is generated by running a single atmospheric dispersion model with the ensemble weather prediction members. In the paper we compare both approaches with the help of statistical indicators, using simulations performed for the ETEX-1 tracer experiment. Both ensembles are also evaluated against measurement data.
