Key Messages Plume-in-Grid Messages –Plume-in-grid has a strong influence on near-field EGU contributions Decreases localized regions of elevated concentration relative to their surroundings for all pollutants: ozone, PM and N & S deposition –In the far field Increases or decreases small contributions depending on chemistry and meteorology Contribution Messages –Non-EGU anthropogenic emissions are key contributors to interstate contributions, particularly to adjacent/bordering states Transport of O 3 and PM has large contributions by non-EGU emissions N Deposition results show important role of non-EGU emissions
