Aqueous Atmospheric Chemistry: From the Molecular to the Regional and Global Scales

Aqueous chemical processes occurring in cloud droplets and wet atmospheric particles are an important source of organic and inorganic atmospheric particulate matter. Despite considerable progress, mechanistic understanding of some key aqueous processes is still lacking, and representation of these processes is incomplete in most regional and global models. I will review the state of the science and discuss my group’s efforts in characterizing these processes in the laboratory, modeling them in detail on the molecular level, and model reduction to include essential processes in large-scale models.
