Southeast Virginia sits under one of the major flight corridors of the eastern U.S., and it’s not unusual to look up and see streaks of line-shaped clouds crisscrossing the sky. These aircraft-made condensation trails, or contrails for short, form when the hot water vapor in the jet engine exhaust cools and condenses onto soot and other atmospheric particles. What’s remarkable about these clouds is that they can have a significant impact on our regional and global climate. In fact, the climate effects of contrails are thought to be more important than the impact from all of the carbon dioxide emitted from aviation ever! Researchers at NASA’s Langley Research Center are exploring how new, bio-based jet fuels can reduce the amount of soot emitted from the aircraft engines and decrease the climate impact of contrail cirrus clouds. Join Dr. Rich Moore as he highlights the exciting results from recent formation flight experiments conducted by NASA and international collaborators.
