Atmospheric nanoparticles formed from heterogeneous reactions of organics
Nanoparticles are a key component of atmospheric aerosols, growing rapidly under ambient conditions. Exposure of nanoparticles to organic vapours shows that various organic species can enhance the
Nucleation and growth of sub-3 nm particles in the polluted urban atmosphere of a megacity in China
Abstract. Particle size distribution down to 1.4 nm was measured in the urban atmosphere of Nanjing, China, in spring, summer, and winter during 2014–2015. Sub-3 nm particle event, which is
Size‐resolved measurements of mixing state and cloud‐nucleating ability of aerosols in Nanjing, China
An integrated aerosol analytical system was deployed in Nanjing, a megacity in the Yangtze River Delta, to measure size‐resolved aerosol mixing states, effective densities, cloud condensation nucleus
Aerosol surface area concentration: a governing factor in new particle formation in Beijing
Abstract. The predominating role of aerosol Fuchs surface area, AFuchs, in determining the occurrence of new particle formation (NPF) events in Beijing was elucidated in this study. The analysis was
Detection of formaldehyde emissions from an industrial zone in the Yangtze River Delta region of China using a proton transfer reaction ion-drift chemical ionization mass spectrometer
Abstract. A proton transfer reaction ion-drift chemical ionization mass spectrometer (PTR-ID-CIMS) equipped with a hydronium (H3+O) ion source was developed and deployed near an industrial zone in
Absorption coefficient of urban aerosol in Nanjing, west Yangtze River Delta, China
Abstract. Absorbing aerosols can significantly modulate short-wave solar radiation in the atmosphere, affecting regional and global climate. The aerosol absorption coefficient (AAC) is an indicator
Rapid modification of cloud‐nucleating ability of aerosols by biogenic emissions
Although secondary organic aerosol formation is well studied, the extent to which oxidation products of biogenic volatile organic compounds condense onto primary aerosols and modify their
