Canadian wildfire smoke transported to US

Canada has already had its share of wildfires this season, and the smoke from these wildfires is slowly drifting south over the United States' Midwest.  The drifting smoke can be seen in this Terra satellite image over Lake Michigan, as well as parts of Minnesota, Wisconsin, Indiana and Ohio. 

The smoke released by any type of fire (forest, brush, crop, structure, tires, waste or wood burning) is a mixture of particles and chemicals produced by incomplete burning of carbon-containing materials. All smoke contains carbon monoxide, carbon dioxide and particulate matter (PM or soot). Smoke can contain many different chemicals, including aldehydes, acid gases, sulfur dioxide, nitrogen oxides, polycyclic aromatic hydrocarbons (PAHs), benzene, toluene, styrene, metals and dioxins. The type and amount of particles and chemicals in smoke varies depending on what is burning, how much oxygen is available, and the burn temperature.  Exposure to any type of smoke should be avoided if possible, but especially by those with respiratory issues, the elderly, and children.

This natural-color satellite image was collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite on June 09, 2015.  NASA image courtesy Jeff Schmaltz, MODIS Rapid Response Team. Caption: NASA/Goddard, Lynn Jenner
