DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1745Z July 12, 2012

Canada:
Numerous large wildfires continue to burn across northern
Alberta/Northwest Territories allowing for copious amounts of smoke
to spread eastward across the majority of Canada. The extent of
the thin-density smoke reaches as far east as Quebec/western New
Brunswick. There are also two distinct thick density ribbons of smoke
that are located mainly in northern Alberta/Saskatchewan. The first
ribbon is thinning out a bit and stretching southward towards the
US. The second ribbon of thick density smoke seems to be attached to
one of the large wildfires in Alberta but continues to expand and travel
east/northeastward. A fairly large area of medium-density smoke was also
present this morning, mainly across Alberta/Saskatchewan, intermixed
with various cloud features.

Majority of the US:
A broad area of thin-density smoke was present this morning across much
of the US extending from California eastward across the central US and
then northeastward across Missouri/Illinois/Indiana and the northern
Great Lakes. Some of the smoke in California could possibly be from
fires burning in Siberia, while most of the smoke is likely from the
wildfires burning in California/Oregon/Idaho.

Alaska:
A ring of mainly medium-density smoke was visible across northern British
Columbia, wrapped around a low pressure system, moving eastward across
northern Alberta. Thin-density smoke extended northward from the low into
eastern Alaska. This smoke could possibly be a combination of smoke from
Siberian fires as well as from the multiple wildfires in Alberta.

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.
