Small, new, remotely-operated, unmanned aircraft are being flown in the Arctic to measure black soot. The soot is produced by burning diesel fuel, agricultural fires, forest fires, and wood-burning stoves. It is transported by winds to the Arctic, where it darkens the surface of snow and ice, enhancing melting and solar warming.
