Short summary

The impact of model horizontal resolution on simulated surface ozone and particulate matter less than 2.5 μm concentrations, and the associated health impacts over Europe, using a coarse (~ 140 km) and a finer (~ 50 km) resolution is examined. Results highlight a strong seasonal variation in simulated O₃ and PM_2.5 differences between the two resolutions and demonstrate that health impact assessments are sensitive to a change in model resolution by up to ±5 % of the total mortality across Europe.
