DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1815Z July 17, 2011

Central and Eastern US:
A large region of aerosol of unknown origin and composition was visible
across the Central US this morning. It is possible that a small amount of
smoke may still be trapped and circulating around the huge ridge of high
pressure covering a large portion of the middle of the country, though it
is more likely that much of the aerosol is composed of other pollutants.

Central and Eastern Canada:
Numerous wildfires continue to burn in western Ontario and eastern
Manitoba.   Moderate to locally dense smoke was produced throughout the
overnight hours and into this morning.   Even though some smoke plumes
are heading south at the surface, winds in the mid-levels are moving the
smoke to the east.   Some of the remnant smoke approached the Quebec/New
England border by late morning and it is possible the smoke is already
mixing with other aerosols near Boston.

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.
