Reem Hannun

Dr. Reem Hannun is an experimental atmospheric chemist within the Atmospheric Science Branch at NASA Ames. Her work broadly focuses on using measurement-based approaches to understand the sources, transformations, and fates of trace gases in the atmosphere that are relevant to air quality and climate. She is particularly interested in research questions that integrate atmospheric chemistry with the greater Earth system, such as biosphere-atmosphere exchange processes (like uptake and emissions by soils and vegetation) and the role they play in mediating atmospheric gases, including carbon dioxide, methane, and ozone.
