Information on the modelling runs. Emissions totals reflect the entire domain. Concentrations and OPEs are averaged over the polygon superimposed
on the inland region of each of the plots in Fig. 2.1 to exclude boundary effects and high OPEs over water. Reprinted with permission from Henneman et al. [5].
