The Terra satellite took this image of the western Canadian wildfires smoke as it headed eastward to Ontario and Quebec. The image also shows that some of the smoke has even drifted a bit southward into the U.S. and is over both Michigan and Wisconsin. The U.S. mid-West has been hit with smoke from both the wildfires in the U.S. West and fires in the Canadian West. The smoke released by these wildfires a mixture of particles and chemicals produced by incomplete burning of carbon-containing materials. All smoke contains carbon monoxide, carbon dioxide and soot, as such any inhalation of smoke should be avoided.
