Remotely Operated Aircraft Measure Arctic Soot

Scientists and engineers at PMEL recently returned from an expedition in the Arctic where they launched two small, new, remotely-operated, unmanned aircraft to measure black soot. The soot is produced by burning diesel fuel, agricultural fires, forest fires, and wood-burning stoves, and is transported by winds to the Arctic, where it darkens the surface of snow and ice, enhancing melting and solar warming.
