Energy Research Area: Our group studies how aerosol formation and the oxidative capacity of the atmosphere change in response to both climate change and anthropogenic activities.
The Earth’s atmosphere is a highly oxidizing medium. The tropospheric abundance of oxidants such as the hydroxyl radical (OH) and ozone (O3) determines the lifetime, and thus the concentration, of most reduced trace gases important to climate (e.g. CH4) and human health (e.g. CO). In addition, atmospheric oxidant abundances can influence the formation pathway of aerosols with implications for their climate effects and for air pollution. Our research examines how tropospheric aerosol and oxidant chemistry varies over time and space. The time scales we consider range from seasonal to glacial-interglacial variability on the global scale. We aim to answer two fundamental questions in atmospheric chemistry:
