DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0330Z August 09, 2012

Western and Central US:
A very large area of thin density smoke from numerous wildfires burning
across portions of the Western US extended from northern California to
southwestern Canada and southeastward from there over the Rockies as
well as the Central and Southern Plains. Moderately dense to thick smoke
covered northeastern California, northern Nevada, eastern Oregon, northern
Utah, and much of Idaho, Montana, and Wyoming. The moderately dense smoke
also moved over southern Alberta and southwestern Saskatchewan in Canada.

Canada/North Central US:
Numerous wildfires burning from northwestern Canada to south central
Canada were responsible for an extensive mass of thin density smoke which
covered a huge part of Canada as well as some of the northern tier of
the US from North Dakota to the western Great Lakes region. Moderately
dense smoke was seen centered primarily over Hudson Bay. Thicker smoke was
generally confined to areas closer to the actual fires. Some cloudiness in
the vicinity of some of the fires did limit smoke detection in satellite
imagery to a certain extent.

Northwestern US/Southwestern Canada:
Thin to moderately dense smoke which is believed to have originated from
ongoing fires in Siberia was visible moving from the Pacific inland over
portions of the Pacific Northwest and British Columbia in southwestern
Canada.

Gulf of Mexico/Florida:
Dust which has moved across the Atlantic from the Saharan Desert could be
seen across a good portion of the Gulf of Mexico as well as the Florida
Peninsula and just offshore of Georgia and South Carolina.

Alaska:
Smoke from the Siberian fires was also visible moving to the east and
southeast over the Bering Sea and into western and northwestern Alaska.

Northwestern Canada:
Several fires continue to burn over northern British Columbia, and
southern parts of the Yukon and Northwest Territories. However, cloudiness
in the region significantly limited smoke detection in satellite imagery.

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.
