Long term air quality trends in Europe ETC/ACM Technical Paper 2016/7

Contribution of meteorological variability, natural factors and emissions

Modelled ozone and particulate matter (PM) trends are compared to observations. Average maps of the evolution between 1990 and 2010 are presented. The attribution analysis demonstrates that emission reductions are the primary driver of both ozone and PM changes. Boundary conditions are mainly important for ozone trends. Depending on the region and pollutant, it can sometimes have a smaller impact than interannual meteorological variability.
