Multiphase Atmospheric Chemistry: From the molecular to the regional and global scales

"Multiphase chemistry in the atmosphere is a major source of organic and inorganic atmospheric particulate matter, and also has a profound influence on gas-phase composition and precipitation chemistry. Despite considerable progress, mechanistic understanding of some key aqueous atmospheric processes is still lacking, and their representation is incomplete in most regional and global models. I will present an overview of aqueous chemical processes in the atmosphere, highlighting recent developments and critical uncertainties. I will also discuss my group’s efforts in characterizing these processes in the laboratory and improving their representation in atmospheric chemistry models."
