Tristan Carion is a mechanical engineer from UCL (Université Catholique de Louvain-la-Neuve) in Belgium. After graduating in 2016, he spent a few years working for the industry. He also spent some time traveling the world. He went back to the academic world in 2020 where he joined the Royal Military Academy of Belgium (RMA) as a researcher. He is working for a joint project of RMA, ECMWF and RMI (Royal Meteorological Institute of Belgium), which consists of implementing atmospheric dispersion models and response models on the ECMWF Weather Cloud and use the ensemble forecasts from ECMWF to produce ensemble dispersion modeling.
Atmospheric dispersion models will be coupled with event-based response models to assess the impact of CBRN (Chemical, Biological, Radiological and Nuclear) releases. A user-friendly web-based tool is being developed using Genie.jl and will run on the cloud infrastructure of ECMWF. The event-based model will be implemented using the SimJulia.jl framework. Ensemble weather forecasts will then be used to give probabilistic quantification of the impacted area and of the appropriate response plan.
