Description
FLEXPART is a Lagrangian particle dispersion transport model which is originally designed for calculating the long-range and mesoscale dispersion of air pollutants from point sources. Through the years, these type of models have proven to be a very useful tool in an operational context for the protection of the population in case of accidents in a nuclear power plant. In the meantime, FLEXPART has evolved into a more comprehensive tool for atmospheric transport modelling and analysis. The model can also be used in a forward or backward mode, making it possible to trace back the source pollution contribution of a certain pollutant.
The FLEXPART model is designed to be operational for the long-range transport and therefore runs on a resolution of 0.5° x 0.5°, using meteorological forecast data from the European Centre for Medium Range Forecasts (ECMWF). On a daily basis, FLEXPART runs at the Royal Meteorological Institute of Belgium for several hotspots for the northern hemisphere. The lead time of the forecast is 3 days.
The presentation will include an overview of the setup of the model and some examples will be discussed.
