Abstract Elucidating the molecular-level evolution of organic aerosols (OA) is fundamental to understanding atmospheric chemistry and its climatic impacts, yet current analytical techniques are often constrained by thermal decomposition and fragmentation artifacts. In this study, we deployed a novel Vaporization Inlet for Aerosols coupled with a Vocus Proton Transfer Reaction Time-of-Flight Mass Spectrometer (VIA-PTR) during a wintertime field campaign in urban Beijing.

Abstract New particle formation has been estimated to produce more than half of the global cloud condensation nuclei and profoundly impacts clouds, climate, and air quality. The initial growth from the cluster size ( ~ 1 nm) to a few nanometers, for which the underlying mechanisms can be very different from the subsequent growth, is the most critical stage for new particles to become climate-relevant.
