DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0330Z July 22, 2012

Canada/Great Lakes Region:
Significant smoke continues to emanate from large fires scattered
primarily across northern Alberta, the southern portion of the Northwest
Territories, north central Saskatchewan, central Manitoba, and west
central Ontario. A huge area of thin density smoke covers a good portion
of western and south central Canada to as far east as western Quebec
province. Embedded within this region are swaths of moderately dense
to thick smoke which are especially prevalent closer to the fires over
eastern Manitoba and western Ontario. Thin to moderately dense smoke
had also spread as far to the southeast as northeastern Minnesota,
Lake Superior, the Upper Peninsula of Michigan, northern Lake Michigan,
and northern Lower Michigan just prior to sunset.

Far Northeastern Canada:
An area of mainly thin density smoke was visible extending from the
Canadian arctic southeastward across far northeastern and eastern Canada,
as well as Baffin Bay, and the Labrador Sea. This detached remnant smoke
may be from the fires burning across south central and western Canada,
but it may also have some contribution from the Siberian fires.

Central US:
Rather large fires were detected over southern South Dakota and Northern
Nebraska which produced thin to locally moderately dense smoke. The smoke
fanned out as it moved to the east, southeast, and eventually to the
south reaching as far as northeastern Kansas. Several large moderately
dense to thick smoke plumes were also visible moving to the west from
fires over Oklahoma.

Northwestern US/Southwestern Canada and Northwestern Canada/Southeastern
Alaska:
A large patch of thin density smoke was visible in between areas of
clouds extending inland from the Pacific across the Pacific Northwest,
the northern Rockies, and southwestern Canada. Another area was seen over
southeastern Alaska and northwestern Canada. This smoke was believed to
be from the ongoing fires in Siberia.

Florida/Western Atlantic/Caribbean:
The leading edge of a huge mass of Saharan dust which moved to the west
across the Atlantic and Caribbean could be seen over central and southern
Florida during the day.

Southern Oregon:
A small patch of blowing dust moved to the east from a dry lake bed in
central Lake County of south central Oregon.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT
AREAS SMOKE ASSOCIATED WITH ACTIVE FIRES AND SMOKE WHICH HAS BECOME
DETACHED FROM THE FIRES AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE
FIRE..TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. AREAS OF BLOWING DUST
ARE ALSO DESCRIBED. USERS ARE ENCOURAGED TO VIEW A GRAPHIC DEPICTION OF
THESE AND OTHER PLUMES WHICH ARE LESS EXTENSIVE AND STILL ATTACHED TO
THE SOURCE FIRE IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE:

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.
