Short summary
New particle formation is an important source of atmospheric aerosols. We conducted size- and time-dependent nucleation rate and growth rate measurements of sub-3 nm particles in the urban atmosphere. We observed that growth rate could be very high between 1 and 3 nm and did not increase monotonically with particle size. This was interpreted as the solvation effect of organic vapor in inorganic nuclei. The growth rate behavior gives new insight into cluster dynamics in polluted environments.
