The plume of carbon monoxide pollution from the Rim Fire burning in and near Yosemite National Park, Calif., is visible in this Aug. 26, 2013 image from the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua spacecraft. The image shows a three-day running average of daily measurements of carbon monoxide present at an altitude of 18,000 feet (5.5 kilometers), as well as its global transport. The abundance of carbon monoxide is shown in parts per billion, with the highest concentrations shown in yellows and reds. The carbon monoxide plume from the Rim fire now extends into Canada. Even more prominent in the image are the carbon monoxide emissions from widespread agricultural fires in Africa and South America, and fires in the northern forests of Asia.
