Conclusion and outlook
Modelling atmospheric transfers of pollutants

Modeling is now widely used to assess the environmental impact of air pollution episodes, to design air monitoring networks and to calculate ambient air concentrations. It is even indispensable for the a priori assessment of the consequences of any atmospheric release of pollutants.

A review of atmospheric transfer codes, whether commercial or developed for research purposes, highlights the existence of a multitude of codes that should be used judiciously.

It appears that there is no ideal tool for handling all types of discharge. Today, therefore, we are moving towards a combination of different types of modeling (Lagrangian modeling with Gaussian puffs, for example, or a platform of various tools) depending on the type of result and simulation required.
