DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0245Z September 2, 2011

Central US:
An expansive area of smoke is observed this evening over much of the
central US including the Northern Rockies, Central plains and the
Mississippi and Ohio River Valleys.  The likely origin of this area of
smoke includes large wildfires in Oregon/Montana/Idaho, large wildfires
in Texas/Oklahoma, and numerous fires over the lower Mississippi River
Valley.

Eastern Great Lakes and Northern Mid-Atlantic:
An unknown area of aerosol was located over the eastern Great Lakes
States and extending south into portions of the northern Mid-Atlantic.
The source for this region is unknown although it's possible that it
contained some remnant smoke from the wildfires over the northern Rockies.

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.
