Szinyei, D. (author), Gelybó, G. (author), Guenther, A.B. (author), Turnipseed, A.A. (author), Tóth, E. (author), Builtjes, P.J.H. (author)In this study, we evaluated three conceptually similar ozone gas deposition models. These dry deposition models are frequently used with chemical transport models for calculations over large spatial domains. However, large scale applications of surface-atmosphere exchange of reactive gases require modeling results as accurate as possible to...article 2018

(author)The impact of large cities on air pollution levels usually is determined with models driven by so-called downscaled emission inventories. This implies that annual emissions of air pollutants at the national scale are spatially distributed over a grid using proxy data like population density. These inventories are frequently used for regional air...article 2013

(author), TNO Bouw en Ondergrond (author)Fine particulate matter (PM) is relevant for human health and its components are associated with climate effects. The performance of chemistry transport models for PM, its components and precursor gases is relatively poor.
