DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1615Z July 18, 2009

Alaska/Canada/North Central US:
Moderately dense to dense smoke continues to emanate from a number
of fires burning across portions of Alaska and the Yukon province of
northwestern Canada. The smoke from these fires has also spread a great
distance over a number of days and was visible across a large portion
of central Canada as well as the northern Mississippi Valley and Great
Lakes. SO2 is likely mixed in with the smoke,especially across the US
and central Canada, but it is not known which one is the dominant type.

Four Corners:
Remnant smoke from fires in Utah and Arizona was detected over the Four
Corners region.

Southern Florida/Northwest Caribbean/Bahamas/Southern Gulf of Mexico:
A large area Saharan dust was apparent stretching from the southern
Bahamas across Cuba and the northwestern Caribbean into the southern
Gulf of Mexico.

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.
