DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1730Z July 25, 2011

Northwest Territories/Nunavut to Northern Quebec/Southeast Canada:
Remnant smoke covers much of northern Canada this morning with most of
the smoke likely originating from the wildfires just east of the Great
Slave Lake. Moderate to dense smoke stretches from the site of the fires
east across southeast Northwest Territories, southern mainland Nunavut,
and northwest Hudson's Bay. Some thin to moderately dense smoke was
also present across the Bay moving over northern Quebec. Further to
the southeast, an unknown aerosol stretched southeast across the
Gulf of St. Lawrence and portions of New Brunswick, Nova Scotia,
and Newfoundland. This aerosol could be several day old smoke from
the NWT wildfires but it cannot be certain. There is also some thin
smoke present over northern portions of the Northwest Territories/north
mainland Nunavut, with the source either being the couple of wildfires
that are in Alaska or the wildfires near Great Slave Lake.

Western to Central Canada:
Aerosols of unknown origin and composition extend across the
southwest/south Northwest Territories, northeast British Columbia,
northern Alberta, north and east central Saskatchewan, and reach into
northern Manitoba. At least some of the aerosol in northern Manitoba is
believed to be smoke, most likely from the wildfires near Great Slave
Lake, but the rest of the aerosol cannot be determined.

Alaska:
Two small patches of thin remnant smoke were seen over east central
Alaska, likely from two wildfires in that region.

Wyoming/Montana/South Dakota:
A small patch of thin to moderate density smoke was seen over northeast
Wyoming, southeast Montana, and northwest South Dakota. This remnant
smoke likely came from the wildfire burning yesterday and today in the
Shoshone National Forest in northwest Wyoming.

Kansas:
An outflow boundary from a large thunderstorm complex over the High
Plains last night could be seen moving across Kansas, southeast Nebraska,
and northwest Missouri. There appears to have been some aerosols along
this boundary over west and central Kansas this morning but the origin
and composition cannot be determined.

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.
