DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1800Z September 24, 2011
Western US: Remnant smoke was seen over portions of the western US this morning. Thin to moderately dense smoke, produced by several wildfires in Wyoming yesterday was seen over western Wyoming and extreme northwest Colorado. Remnant smoke from fires in Oregon and northern California was seen lifting north/northeast across portions of Oregon and Washington as well into southern British Columbia. North Central Canada: Aerosol could again be seen this morning moving across northern Hudson Bay. This is the same aerosol that has been seen moving across Northwest Canada the past two days. A small portion of the aerosol could also be remnant smoke from recent fires in the Northwest Territories around Great Slave Lake and in northern Alberta. South Central Canada: Small patches of thin remnant smoke were present over central Manitoba moving eastward. This smoke is probably from fires yesterday in southeast Saskatchewan and southern Manitoba. A larger area of aerosol could be seen over southern Quebec/southeast Ontario beneath some cloudiness, but the composition or origin of this aerosol could not be determined. British Columbia Coast/Northwest Canada: A plume of aerosol was again present today in GOES-W imagery off the coast of British Columbia extending northeast across the northern part of the province to the southwest corner of the Northwest Territories. There is a possibility that this aerosol is SO2 from volcanoes in the Kamchatka Peninsula, Russia. Sheffler THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS SMOKE ASSOCIATED WITH ACTIVE FIRES AND SMOKE WHICH HAS BECOME DETACHED FROM THE FIRES AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE FIRE..TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. AREAS OF BLOWING DUST ARE ALSO DESCRIBED. USERS ARE ENCOURAGED TO VIEW A GRAPHIC DEPICTION OF THESE AND OTHER PLUMES WHICH ARE LESS EXTENSIVE AND STILL ATTACHED TO THE SOURCE FIRE 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 ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO SSDFireTeam@noaa.gov
