DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1600Z September 12, 2009
South Central Canada/Great Lakes Region/Upper Mississippi Valley/Ohio Valley: An area of aerosol was once again visible this morning in GOES-West imagery with the favorable low sun angle just after sunrise covering portions of south central and southeastern Canada, the Great Lakes Region, the Upper Mississippi Valley, and the Ohio Valley. The aerosol was trapped under the persistent upper level ridge which has been present for days in this region. It is possible that some of this aerosol is still composed of old remnant smoke from the larger fires which had been burning in southern British Columbia Province of southwestern Canada and also southern California. However, since it has been quite a few days since these fires have been particularly intense, this aerosol is no longer being depicted as smoke in the graphic products found on the links below. JS More information on the areas of smoke described above as well as others can be found at the locations listed below. 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
