TL;DR: In this article, a physicochemical characterization, including aerosol number size distribution, chemical composition and mass concentrations, of the urban fine aerosol captured in MILAN, BARCELONA and London is presented.

TL;DR: In this article, Doppler lidar observations of turbulence profiles in the centre of London, UK, as part of the second REPARTEE campaign in autumn 2007 were reported.

TL;DR: In this article, the nucleation mode aerosol was characterized during coastal nucleation events at Mace Head during intensive New Particle Formation and Fate in the Coastal Environment (PARFORCE) field campaigns in September 1998 and June 1999.

TL;DR: In this paper, three cities located in predominantly sunny environments: Barcelona (Spain), Madrid (Spain) and Brisbane (Australia) were systematically studied three long-term data sets (1-2 years) of fine and ultrafine particle number size distributions (measured by SMPS, Scanning Mobility Particle Sizer) were analyzed.

TL;DR: It is argued that dedicated research is required on nonexhaust emissions and dispersion to urban areas from both an air quality and a public health perspective and the implicated message to regulators and policy makers is that road transport emissions continue to be an issue for health and air quality, despite the encouraging rapid decrease of tailpipe exhaust emissions.
