|Shown above is the visible satellite from Thursday afternoon, August 5th. What appears to be a very thin veil of clouds across North Dakota is actually smoke in the upper levels of the atmosphere from fires in British Columbia. Smoke from these fires rise into the upper atmosphere, and are transported downstream by upper level winds aloft. Shown below is an analysis of significant fires, and the transport of the associated smoke. This image is courtsey of the NOAA Satellite and Information Service.
