DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0345Z July 2, 2009

Southwest Canada:
A band of SO2 stretches to the east-northeast from Vancouver Island
across southern British Columbia, southern Alberta, and southern
Saskatchewan. Another band of SO2 stretches to the east across central
British Columbia and central Alberta before wrapping northeastward over
northwest Saskatchewan. Both bands are roughly 50-100km wide.

Northern Plains/Midwest/South Central Canada:
A band of thin to moderately dense smoke likely mixed with SO2, was still
positioned from southern Manitoba southward into eastern North and South
Dakota, western Minnesota, western Iowa, Missouri, southern Illinois,
western Kentucky, and western Tennessee. The hazy appearance from this
smoke and SO2 was pinned along the back edge of an upper level trough
that has been moving very little over the past few days.

Central to Southern Plains:
Thin to moderately dense smoke and haze covered parts of Kansas, Oklahoma,
Arkansas, Texas, Louisiana, Mississippi, and Alabama this evening. Much
of this smoke was leftover from the numerous fires that were burning
yesterday across Kansas and Oklahoma, though smoke from active fires in
the same areas today was also being added to the mixture of aerosols.

Colorado/New Mexico/Texas and Oklahoma Panhandles:
Wispy areas of thin to moderately dense smoke were observed moving
southeastward across southeast Colorado and northeast New Mexico into
the panhandles of Texas and Oklahoma. It is believed that most of this
smoke was produced by fires in Utah and Colorado yesterday, with the
fire in western Colorado still producing smoke today.

Alaska:
A concentrated area of remnant SO2 from volcanic activity was seen
this evening over the Aleutians and the southwest to northwest parts
of Alaska. Some SO2 was also still present over northeast Alaska and
the northern part of the Yukon Territory. Some thin smoke was also seen
over central Alaska but it was mixing with the SO2 and was not as easy
to identify this evening.

Northeast Canada:
A large wildfire north of Wabush Lake near the Quebec/Labrador border
was producing an approximately 200km long plume of very dense smoke that
was spreading northwestward.

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.
