DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z July 9, 2009

Alaska/NW Canada:
Smoke covers much Alaska south of the Brooks range and east of a line
roughly from McGrath to Galena with large areas of dense smoke. The
smoke also extends south into the northern Gulf of Alaska between Kodiak
Island and Sitka and southeast into the southern Yukon and northern
British Columbia.

California to Wyoming:
A thin ribbon of likely sulfur dioxide (SO2) was seen this prior to
sunset extending from the San Francisco Bay area northeastward across
Lake Tahoe, to the northeast corner of Nevada, the northern portion of
the Great Salt Lake and into north central Wyoming.

Southern California to southwest Arizona:
A mix of smoke from numerous fires in the agricultural area south of the
Salton Sea and blowing dust was moving to the northeast into southwest
Arizona.

Quebec:
An area of thin aerosol, believed to be SO2, covered the area on the
southeast shore of Hudson Bay and James Bay and then curling to the
southeast to near Montreal.

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.ssd.noaa.gov/PS/FIRE/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






 


Unless otherwise indicated:
  • Areas of smoke are analyzed using GOES-EAST and GOES-WEST Visible satellite imagery.
  • Only a general description of areas of smoke or significant smoke plumes will be analyzed.
  • A quantitative assessment of the density/amount of particulate or the vertical distribution is not included.
  • Widespread cloudiness may prevent the detection of smoke even from significant fires.
