AB: We present evidence that boreal forest fires represent a major source of soot in the stratosphere, affecting stratospheric temperature and chemistry and global radiative forcing. Polluted air unambiguously attributable to forest fires in North America was observed at altitudes up to 15.8 km, demonstrating direct transport of heavy smoke from the surface deep into the stratosphere which is not captured by atmospheric transport models. Stratospheric soot may not be due primarily to aircraft exhaust, as currently believed, but may be sensitive to changes in forest burning associated with climatic warming.
