Deposition and nitrogen budget
The deposition of acidifying and eutrophying components and crop damage due to ozone fluxes are still a major issue in the field of atmospheric pollution.
LOTOS-EUROS contributes to high-resolution deposition studies. It is one of the few models with a compensation point – the concentration of a given component at which atmospheric uptake equals deposition. This means that the deposition of ammonia depends on the presence of an ammonia reservoir at ground level and re-emission may even occur.
