Jeff Geddes

Dr. Geddes’ research group is focused on the impacts of reactive trace gases in Earth’s atmosphere. Topics range from understanding urban air quality to studying biosphere-atmosphere exchange in natural environments. The group primarily uses satellite remote sensing observations in combination with a global model of atmospheric chemistry, but also relies on field measurements. Current projects explore urban-scale variability in remote sensing of surface air quality; interannual variability in biosphere-atmosphere trace gas exchange; and the impacts of land use change on atmospheric chemistry.

Expertise: Urban air quality, remote sensing
