ESIAS

Both EURAD-IM and WRF are extended by an ensemble setup within the Ensemble for Stochastic Integration of Atmospheric Simulations (ESIAS). This ensemble system can provide pure ensemble forecasts and ensemble data assimilation analysis to enable the investigation of forecast uncertainties. New ensemble data assimilation techniques are developed within ESIAS to analyse the influence of input data to the predictability. The complexity of the models and the inversion methods enforce the application of high performance computing facilities as they are hosted at Forschungszentrum Jülich.
