UDINEE - Urban Dispersion International Evaluation Exercise


The main aim of UDINEE is the evaluation of Atmospheric Dispersion Models (ADMs) that are or can be used in urban environment as Decision Support Systems (DSS) following Radiological Dispersion Device (RDD) events. The fact that there exist several types of ADMs in terms of formulation, application methodologies and types of outputs mean that these differences have to be assessed as they may lead to different conclusions and decisions.

The UDINEE project will:

  • verify and evaluate the capacities of dispersion models to simulate realistic RDD scenarios in urban environments;
  • assess the real capacity of these systems to respond to an emergency under many aspects such as: timeliness of the prediction, accuracy of the prediction, and in the presence of limited inputs;
  • support the use of local models for decision making and policy development;
  • extend an existing model evaluation platform to urban models that would favour a more regular evaluation of modelling tools in this complex situation;
  • improve and develop common model formats for the rapid and coherent exchange of information across countries and produced by different modelling systems;
  • define under what circumstances (urban environment characteristics, meteorological conditions, horizontal and vertical resolutionÂ…), given the current state of the science, it would be optimum in an emergency situation to use ADMs, and what other methods should be envisaged to complement missing aspects not yet covered by currently available modelling systems.
