Aerosol formation via aqueous-phase chemical reactions

simpleGAMMA – a reduced model of secondary organic aerosol formation in the aqueous aerosol phase (aaSOA)

Insights into secondary organic aerosol formed via aqueous-phase reactions of phenolic compounds based on high resolution mass spectrometry

Recent work has shown that aqueous-phase reactions of phenolic compounds – phenol (C6H6O), guaiacol (C7H8O2), and syringol (C8H10O3) – can form secondary organic aerosol (SOA) at high yields. Here we examine the chemical characteristics of this SOA and its formation mechanisms using a High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-AMS), an Ion Chromatography system (IC), and a Tot...

Aqueous aerosol SOA formation: impact on aerosol physical properties.

Organic chemistry in aerosol water has recently been recognized as a potentially important source of secondary organic aerosol (SOA) material. This SOA material may be surface-active, therefore potentially affecting aerosol heterogeneous activity, ice nucleation, and CCN activity. Aqueous aerosol chemistry has also been shown to be a potential source of light-absorbing products ("brown carbon")...

Interactive comment on “ simpleGAMMA – a reduced model of secondary organic aerosol formation in the aqueous aerosol phase ( aaSOA ) ”

The authors present a reduced version of their previously published GAMMA model (Gas-Aerosol-Model for Mechanism Analysis) that targets secondary organic aerosol (SOA) formation in aerosol water. The current study presents a reduced version of the model to be implemented in regional and global models that cannot include as much detail as the full GAMMA. SOA formation in the aqueous phase is not...
