DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1630Z July 21, 2012
Northern Great Lakes: Remnant medium-density smoke moved over Lake Superior and the Upper Peninsula of Michigan this morning. The smoke was located behind a frontal boundary in the area. This smoke moved southeastward from the numerous wildfires in Canada, especially eastern Manitoba and western Ontario. Central Canada: A swath of smoke, approximately 325 km wide in places, extended from central Manitoba to the Northwest Territories. The smoke in this area is mainly from the Canadian wildfires because some Siberian smoke could be present. Alaska/Yukon: Even though cloud cover is extensive, an area of remnant smoke was seen this morning along the Alaska/Yukon border. It is likely this smoke is from Siberia and was transported across the Pacific Ocean.
