Short summary
The largest source of ultrafine (UF) aerosol particles in cities seems to be vehicular road traffic. We quantified here that nucleation generates 37 % of UF particles in the near-city background, and 13 % in the city centre. This implies that the health-related consequences of atmospheric new particle formation and growth processes in cities should also be considered in addition to their urban climate implications.
