DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0245Z August 27, 2011

Pacific Northwest/Northern Rockies to the Great Lakes States and Southern
Ontario and Southwestern Quebec:

A large area of thin to locally moderately dense smoke was analyzed
from the Pacific Northwest and Northern Rockies and extending east to
the central and Northern Plains, Great Lakes States and into portions of
southwest Quebec.  Additionally, it appeared as though the smoke extended
south into portions of the Southern Plains and into Texas and New Mexico.
It is believed that the source for the majority of this area of smoke
is the numerous wildfires currently occurring over the Pacific Northwest
and Northern Rockies.

Gulf Coast States to Texas:
A large area of mostly thin aerosol was located along the Gulf Coast
States from Georgia and extending towards Texas.  The source for this area
of aerosol is believed to be a combination of the fires in the Pacific
Northwest and Northern Rockies, a number fires that have occurred the
last several days over the southern Mississippi Valley and also possibly
an area of remnant Saharan Dust.

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.
