Abstract

Atmospheric oxidation is the process by which the atmosphere cleanses itself of surface emissions of gases and particles. Hydroxyl (OH) along with nitrate (NO₃) and ozone (O₃) drive atmospheric oxidation. A decade of studies have suggested that measured OH is 2-10 times modeled OH in forest environments, which are globally widespread and thus important. At the same time, other studies have shown that model calculations of ozone production are not the same as measurements, which is important for improving urban air. Some new ways to look at atmospheric oxidation show promise to shed light on these problems.
