Smoke from Alberta Streams into the United States

Smoke from Alberta Streams into the United States

The fire that devastated Fort McMurray in the Canadian province of Alberta generated pyrocumulus clouds that lofted smoke high in the atmosphere. Winds then transported plumes of this smoke long distances. On May 8, 2016, the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi-NPP satellite captured an image of northwesterly winds pushing smoke over North Dakota, South Dakota, and Minnesota. The smoke triggered warnings about unhealthy air in these states.
