Short summary

In this study, we used a Single Particle Aerosol Mass Spectrometer and a Single Particle Soot Photometer to investigate the chemical and physical properties of black carbon (BC) aerosols during a regional air pollution episode in urban Shanghai. BC containing particles were mainly attributed to biomass burning and traffic emissions. We observed a group of highly aged traffic emitted particles with a relatively small BC core (~ 60–80 nm) and a very thick absolute coating thickness (~ 130–300 nm).
