NASA’s DC-8 aircraft flies low over Los Angeles, as scientists onboard collect data on urban emission and atmospheric chemical reactions. The project will continue its investigations flying at low altitudes over Chicago, New York, and Toronto to measure pollution sources and their effects on climate and air quality.
