The three-year running mean of PM2.5 concentrations (2009–2011) is calculated as the average over all operational (sub)
urban background stations within a Member State in the period 2009–2011. The orange dots correspond to AEI-values as
provided by the EU Member States in the air quality questionnaire (reporting year 2011; reference period 2009–2011 except
Poland: reference period 2010–2011).
