DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1515Z July 07, 2010
Northern and Central Canada/N-Central U.S.: A thin, elongated area of remnant smoke from fires in northern Saskatchewan and Manitoba stretches north to south over portions of north and central Canada and is even seen as far south as North Dakota. The area of smoke is visible over western Nunavut, central Northwest Territories, northwest Alberta, western and southern Saskatchewan, southwestern Manitoba and then crosses the border over northern and southwestern North Dakota. Widespread dense cloud cover is likely preventing the ability to analyze the full extent of the smoke across central Canada this morning. A second area of thin smoke was seen across central Manitoba and it is possible that it is connected to the larger smoke area to its west, but clouds prevented the ability to see if is truly connected. Eastern Canada: An area of remnant smoke that also originated from the fires in northern Saskatchewan and Manitoba was seen in visible satellite imagery over northeastern Ontario, Quebec and southern Hudson Bay. Lower Great Lakes/Ohio Valley/Mid-Atlantic Region/Northeast/Southeast: A broad area of optically thick aerosol believed to be mostly ozone continues to be seen circulating clockwise over this region under a persistent upper level ridge axis. Earlier in the week some of this aerosol was analyzed as smoke from fires in Canada, so there is a possibility that there still may be some very thin residual smoke trapped under the stagnant ridge axis and mixed in. The aerosols stretched Indiana east to the Mid-Atlantic region and much of the northeast. Texas: An area of unknown aerosol was seen this moving over central TX, near Abilene moving slowly northeast. Warren THE FORMAT OF THIS TEXT PRODUCT IS BEING MODIFIED. IT WILL NO LONGER DESCRIBE THE VARIOUS PLUMES THAT ARE ASSOCIATED WITH ACTIVE FIRES. THESE PLUMES ARE DEPICTED IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE: JPEG: http://www.osdpd.noaa.gov/ml/land/hms.html GIS: http://www.firedetect.noaa.gov/viewer.htm KML: http://www.ssd.noaa.gov/PS/FIRE/kml.html THIS TEXT PRODUCT WILL CONTINUE TO DESCRIBE SIGNIFICANT AREAS OF SMOKE WHICH HAVE BECOME DETACHED FROM AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE FIRE, TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. IT WILL ALSO STILL INCLUDE DESCRIPTIONS OF BLOWING DUST. ANY QUESTIONS OR COMMENTS REGARDING THESE CHANGES OR THE SMOKE TEXT PRODUCT IN GENERAL SHOULD BE SENT TO SSDFireTeam@noaa.gov
