DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1815Z August 10, 2015

SMOKE
West Coast/Pacific Northwest and North Central US/Southwestern and South
Central Canada:
A large area of light to moderately dense smoke is present across much
of the western US and southwest/south central Canada. Smoke extends
north/northeast from central California to southern British Columbia,
southern Alberta, southern Saskatchewan, and southwest Manitoba. The smoke
then spills southeastward across parts of the north central US including
Montana, the Dakotas, Minnesota, Wisconsin, Iowa, and the U.P. of
Michigan. The bulk of this smoke is from numerous wildfires burning in
northwest California and southwest Oregon that is being carried to the
northeast. There may also still be some remnant Siberian smoke in the mix,
particularly across south central Canada and the north central US.

Oregon/Idaho/Nevada/Utah/Wyoming/Colorado:
Remnant smoke from the Willow wildfire near the Arizona/California border
and smoke possibly from other Arizona fires yesterday continues to drift
to the northeast and now extends from eastern Oregon east across southern
Idaho, northeast Nevada, north Utah, southern Wyoming, north Colorado,
and southwest Nebraska.

Northwestern and Northern Canada/Labrador Sea/Southern Greenland/North
Atlantic:
An expansive area light with embedded moderately dense smoke is seen
over the northern Yukon territory, much of the Northwest Territories,
Nunavut, central and northeast British Columbia, north Alberta, north
Saskatchewan, north Manitoba, and northern Hudson Bay.  The smoke extends
east across far northern Quebec over the Labrador Sea, far southern
Greenland, and over part of the far north Atlantic. Much of the smoke,
particularly over northwest Canada is believed to be from wildfires
near Great Slave Lake and some smoke from US fires lifting up from the
south has likely mixed with other (possibly Siberian) smoke over parts
of western Canada. Smoke further east across north Canada is a mixture
of Siberian smoke and northwest Canadian smoke.

DUST
Aerosol over the western Gulf of Mexico and south central US/lower
Mississippi River Valley is thought to be Saharan dust. This dust extends
north to southern Oklahoma, Arkansas, Mississippi, and Alabama before it
disappears beneath clouds. Some remnant dust may also be present further
north over parts of Missouri, Illinois, and Iowa though scattered clouds
make distinct determination of the aerosol difficult.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS
OF 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.
