Air quality in sub-Saharan Africa

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.

Regional climate response to changes in regional aerosol emissions

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.

Group field trip to NYSDEC Air Monitoring site

The whole group visited the NYSDEC Air Monitoring site in Queens, NYC. We were hosted by Santosh Mahat and Eric, site engineers for air quality. We have been working with this site since 2019, and returned to co-locate some additional air quality sensors. We also got a tour of their great equipment at both the NCore site and the Near Roadway site!
