DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0445Z July 01, 2010

Alaska/Northwestern and Central Canada:
A large area of moderately dense to dense smoke continues to be visible
spreading to the west across the Yukon and Northwest Territories of
northwestern Canada, northern Alaska, and the Arctic Ocean.  This smoke
was primarily believed to be leftover from large fires scattered over
northern Saskatchewan Province of central Canada.  It is likely that
even more smoke was present across northwestern and north central Canada,
but cloudiness prevented detection in satellite imagery.

Central to Eastern Canada:
Widespread wild fires over northern Saskatchewan and northern Manitoba
were combining to produce a large and extremely dense smoke plume from
northern Saskatchewan and extending into northern Manitoba and southern
Nunavut.

Leftover thin smoke likely from fires which had been burning over Quebec
Province and the fires mainly in northern Saskatchewan Province was
visible in evening satellite imagery across portions of northeastern
Ontario, James Bay and northwestern Quebec.  Widespread cloud cover
prevented further detection of smoke in this region.

Central US to Mid Atlantic Region to off the Northeast Coast:
A very thin area of aerosol which is likely at least partly composed of
leftover smoke were seen extending in a narrow band from Arkansas and
Oklahoma eastward to the Carolinas. Cloudiness farther to the south over
the South Central and Southeastern US interfered with smoke detection
in satellite imagery.  These patches of leftover smoke were believed to
be from the fires burning in northern Saskatchewan Province of central
Canada and Quebec Province of southeastern Canada.

Northern Plains/southern Manitoba/southwestern Ontario:
A very thin area of aerosol that is believed to be remnant smoke from
fires over the Desert Southwest was analyzed from the Dakotas extending
northeast into southern Manitoba and southwestern Ontario.

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.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

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.
