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’s (EPA) 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 four-part webinar series.

Webinar Series Dates & Featured Speakers

Monday, Oct. 31

Topic: Changing chemistry over time
In simple models, particles have often been represented as individual species floating around with no interactions, but real particles in the atmosphere have been observed to mix with other gas and particulate species. Through processes like physical layering or chemical reaction, one species can be partially or fully covered by one or more other species. These presentations will cover how black carbon can mix with other gas and particulate species in the atmosphere and change over time.

Spyros Pandis, Carnegie Mellon University Center for Atmospheric Particulate Studies
Black Carbon, Air Quality and Climate: From the Local to the Global Scale

Monday, Nov. 7

Topic: Accounting for impact, emissions, and uncertainty
Black carbon absorbs light as heat, which can affect the climate. When black carbon is aloft, it can warm the air and instigate changes in rain and cloud patterns; black carbon on snow can speed up melting. These presentations will highlight new research on black carbon behavior, how fuel type and cookstove use changes emissions in developing areas, and how black carbon deposition on snow affects climate.

BC and Other Light-Absorbing Impurities in North American Great Plains Snow: Sources, Impacts, and a Comparison with North China Snow

Monday, Nov. 21

Topic: 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, Dec. 9

Topic: 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.
