DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z July 23, 2011
Eastern Northwest Territories: Several wildfires just east of the Great Slave Lake were emitting moderately dense to dense smoke which moved mainly in a northerly direction during the day. Central and Eastern Canada: At least one patch of wildfires was still active in western Ontario producing a large area of smoke which moved to the east along the southern portion of James Bay and over central Quebec. The smoke was dense closer to the fire, but cloudiness across the region did interfere with additional smoke density and extent information in satellite imagery. Central US to Mid-Atlantic States/Northeast and Offshore: A large area of aerosol was visible in the region stretching from the Middle Mississippi Valley eastward through the Ohio Valley region to the Middle Atlantic and the Northeast. The aerosol extended eastward from there well off the coast over the Atlantic. Given the recent atmospheric flow and trajectories, it is believed that smoke is not a major component of this aerosol. Southwestern US: Fires in northeastern San Diego County and just south of the border in extreme northern Baja were emitting moderately dense to dense smoke which spread to the northeast while thinning out and combining into a larger plume which moved int extreme southern Nevada and western Arizona. JS 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
