CbrnAlert: Web Application for Near Real-Time Dispersion Modelling of CBRN releases

CbrnAlert: Web Application for Atmospheric Dispersion Modelling of CBRN releases in EWC

In the event of a CBRN (Chemical, Biological, Radiological or Nuclear) agent release, fast and effective response is critical for improving consequence management. That is why a very simple procedure (ATP-45) is still being used today by most European countries, to model such releases for the real-time emergency decision making process. Currently, the main drawbacks that make more complex atmospheric dispersion models ill-suited for real-time emergency response are their high computational cost, the need for detailed meteorological data as input, and the expertise required to operate them.

 

CbrnAlert project

The goal of the CbrnAlert project is to provide an EWC-hosted web platform, on which can be modelled CBRN releases using the FLEXPART particle dispersion model. The app is designed such that any individual within the chain of command could easily run the model and dispatch the key results, while the EWC provides the high computational power needed as well as rapid access to the latest ECMWF forecasts. The user can also select a probabilistic approach, which uses ensemble input data for the dispersion model, thus providing valuable information about concentration uncertainties in the results. Current developments include the implementation of additional release types, and response elements (optimized routes for victim transport, number of ambulances needed, etc.) based on the dispersion results and other parameters like population density, nearby hospitals, ground military units, etc.

You can find more details from the presentation at the 7th EWC User Workshop 2024.
