DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1815Z July 1, 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, is
positioned from southeast Saskatchewan and southern Manitoba, south
into eastern North and South Dakota, western Minnesota, western Iowa,
Missouri, and southern Illinois. This allowed for a very hazy look to
the visible satellite imagery from GOES-11 across the northern Plains
and some of the Midwest as the haze was pinned along the back edge of
an upper level trough.

Central to Southern Plains:
Thin to moderately dense smoke and haze covered much of Nebraska, Kansas,
Oklahoma, Arkansas, and north Texas this morning. Much of this smoke
likely was caused by the numerous fires that were burning yesterday
across Kansas and Oklahoma.

Utah/Colorado/New Mexico:
Wispy areas of thin to moderately dense smoke were observed moving
southeastward across Colorado and New Mexico this morning, while smoke
over Utah was moving eastward. It is believed that most of this smoke
was produced by fires in Utah and Colorado yesterday.

Alaska:
Remnant thin to moderately dense smoke seen over eastern Alaska last
evening had spread southwestward across the state by this morning. In
addition, remnant SO2 from volcanic activity apparent over the Aleutians
and the southwest corner of the state, as well as over northeast Alaska
and the northern part of the Yukon Territory.

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.
