Black carbon enters the air when fossil fuels and biofuels, such as coal, wood, and diesel are burned. Since black carbon readily absorbs heat from sunlight, the particles can affect Earth's climate, especially on a regional scale. Though global distribution of soot remains difficult to measure, NASA researchers use satellite data and computer models to better understand how these short-lived particles influence Earth's climate, cryosphere, and clouds. This scientific data visualization uses data from the GEOS5 GOCART climate model to show black carbon's atmospheric concentration from August to November in 2009.A flat map version of this animation is available.This visualziation was created in support of a presentation at the Fall 2009 American Geophysical Union (AGU) conference in San Fransisco, CA.
