Roadmap

FLEXPART was originally developed to simulate the dispersion of dangerous substances from point sources and was validated for such applications with data from continental-scale tracer experiments. It was then used for case studies of intercontinental air pollution transport, also from forest fires. It was also used as a forecast tool for flight planning during field missions and for Lagrangian climatologies of global pollution transport, stratosphere-troposphere exchange and the global water cycle (Stohl., 2006; https://doi.org/10.1029/2005JD006888).
