Research
The Atmospheric Chemistry group, led by Prof. Colette Heald, investigates the composition and chemistry of the global atmosphere and how these impact and interact with air pollution, climate change, and ecosystem health.
We use observations of the atmosphere from all scales (in situ to satellite) with global models of chemistry and climate to study these questions. We also measure biosphere-atmosphere fluxes of reactive species. Research led by Dr. Uli Krieger uses single particle levitation techniques to study aerosol properties.
Research themes in our group:
Modeling tools used by our group:
- The external page GEOS-Chem global chemical transport model: a grass-roots community chemical transport model used by > 100 groups world wide. This model enables process-based exploration of atmospheric chemistry and detailed evaluation against field and satellite observations.
- The external page Community Earth System Model (CESM): a global community earth system model, developed at NCAR with community input. This model enables us to study how atmospheric chemistry interacts with the evolving climate, as well as changing land scapes and vegetation.
