Short summary
Exposure to particulate matter (aerosols) is the most important environmental risk factor relating to negative health impacts. Understanding the sources of aerosols is thereby of great importance. This paper compares modelled aerosol source contributions to those from three European observationally derived datasets. Urban-scale modelling is shown to be impactful, although modelling of aerosols from some anthropogenic sources remains challenging.
