Black carbon is the sooty material emitted from combustion processes, and it can affect human health and the climate. Its role in the atmosphere is broad and complex. In 2010, the U.S. Environmental Protection Agency (EPA) Science to Achieve Results (STAR) program awarded ten grants to universities and organizations to address Black Carbon’s Role in Global to Local Scale Climate and Air Quality. Grantees focused on various black carbon research issues, such as better accounting for emissions and uncertainty, tracking how black carbon “ages” or reacts in the atmosphere, and better representing its ability to impact cloud droplet formation.? Highlights from the research findings will be summarized in this webinar series.

Monday, November 21: Interactions with water
Cloud formation is driven by how a particle attracts water over time. A particle’s water uptake – or hygroscopicity – can also affect how effectively it can deposit itself in the lungs, making this both a climate and health issue. These presentations will discuss advances in research regarding black carbon water uptake.

Friday, December 9: Representation at different geographical scales
The inclusion of better descriptions of black carbon (e.g. including brown carbon) will improve model predictions of both concentration and absorption. These researchers worked to improve black carbon representation in global, regional, and point-level models.
