Dispersion modelling using ensemble forecasts, compared to ETEX measurements
Uncertainties in dispersion modelling due to errors in the meteorological input data have been evaluated by using ensemble forecasts. The ensemble forecasts represent uncertainties generated by analysis errors. A temporal and spatial difference in the dispersion model forecast was found, showing the models dependence on the meteorological input data. The calculations from the dispersion model have been compared to measurements from the European tracer experiment (ETEX). The modelled dispersion fits well to the measured dispersion of the tracer. However, small discrepancies between modelled and measured tracer dispersion suggest a revision of the models dispersion scheme within the atmospheric boundary layer.
