Reconcialiting National Forecasts of Atmospheric Dispersion (ENSEMBLE)
In case of another Trans-boundary scale nuclear accidents affecting Europe, National Long-range
dispersion forecasts will inevitably differ because of differences in national models, differences in weather
prediction methods, and differences in national emergency management strategies. However, difference in national
long-range dispersion forecasts may cause problems at the European level, as National emergency management
strategies based solely on national forecasts may not cohere with those in neighbouring countries.
ENSEMBLE addresses the issue of harmonisation and coherence of emergency management and decision-making in
relation to long range atmospheric dispersion modeling.
