We contribute to the development and application of the international GEOS-Chem Model for research into air quality and climate change.

People and Projects Applying GEOS-Chem:

Randall Martin: Co-Model Scientist

Brian Boys: Trends in global satellite-based PM2.5.

Matthew Cooper: Understanding ozone and HNO3 in the upper troposphere using satellite (ACE, OSIRIS, IASI), and aircraft (MOZAIC, TC4) observations.

Betty Croft: Aerosol scavenging, nuclear accident simulation.

Nat Egan-Pimblett: Changes in North American exposure to PM2.5 over the last couple decades.

Jeffrey Geddes: Trends in exposure to traffic emissions over the last few decades

Melanie Hammer: Simulation of the absorbing aerosol index.

Shailesh Kharol: Examining ground-level NO2 concentrations.

Colin Lee: Sensitivity of global aersol-induced mortality to emission sources.

Chi Li: Simulation of Decadal trends in PM2.5. Member of GEOS-Chem Support Team

Andrew Morrow: Diurnal variation in North American aerosol.

Sajeev Philip: Interpreting satellite observations for Air quality.
