Abstract. The Lagrangian particle dispersion model FLEXPART was originally (about 8
years ago) designed for calculating the long-range and mesoscale dispersion
of air pollutants from point sources, such as after an accident in a nuclear
power plant. In the meantime FLEXPART has evolved into a comprehensive tool
for atmospheric transport modeling and analysis. Its application fields were
extended from air pollution studies to other topics where atmospheric
transport plays a role (e.g., exchange between the stratosphere and
troposphere, or the global water cycle). It has evolved into a true community
model that is now being used by at least 25 groups from 14 different
countries and is seeing both operational and research applications. A user
manual has been kept actual over the years and was distributed over an
internet page along with the model's source code. In this note we provide a
citeable technical description of FLEXPART's latest version (6.2).
