With support from the National Science Foundation and the US State Department, we have started an air quality monitoring network in Kinshasa, DR Congo, a megacity with population over 11 million which suffers from poor air quality yet has no monitoring infrastructure. Other projects include air quality knowledge capacity building in Accra, Ghana (partner with Ghana EPA), sensor deployments in Nairobi, Kenya, Kampala, Uganda, and Lomé, Togo, and using models and remote sensing techniques in India, China, and sub-Saharan Africa.

We are key members of the Regional Aerosol Model Intercomparison Project, or RAMIP as well as the Heterogeneous Climate Forcing project or HETCLIF. Some topics we have worked on in the past include: 1) The impact of changes in emissions in specific regions on local and remote climate, 2) Aerosol impacts on clouds and precipitation and 3) The effect of absorbing aerosols on tropical monsoon systems.
