ENSEMBLE for ECURIE

The ENSEMBLE activity is a part of the Joint Research Centre institutional support activity to DG-TREN. It consists of a network of 22 institutions operating 24 long range atmospheric transport and dispersion models, which differ in terms of concept and numerical code and make use of various numerical weather forecasts. The model predictions produced by these institutions are collected on the ENSEMBLE system located at Joint Research Centre in Ispra. A web facility allows the remote users to consultant in real-time and independently the model results present on the system. The report is devoted to the first application of the new version of the ENSEMBLE system in an international event the ECURIE exercise. It contains the description of the simulation results provided during the exercise with particular emphasis on the new features of the ENSEMBLE system. The model predictions were presented on dedicated, specially established web site for the ECURIE Competent Authorities.
