Exploring the formation of secondary aerosols in elemental carbon at the lower free troposphere
Description
In this study, we studied the chemical components, potential contribution and mixing state of element carbon (EC)-containing particles using a single particle aerosol mass spectrometer (SPAMS) with high-time resolution in the western summit of mountain Hua (Mt. Hua), and further investigated the role of EC in the formation and evolution of secondary aerosols. Combined the results of back trajectories and concentration-weighted trajectory, the effect of regional and upward transport on the chemical characteristics of different EC-containing particles revealed in this study, which improve our knowledge and understanding of its role in the formation of secondary aerosols in the lower free troposphere. The findings from this study provide a new perspective for discussing the EC types and environmental effects in troposphere ambient.
