DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0330Z July 24, 2012

Southeastern United States:
Saharan dust was visible across portions of Florida, Alabama, Mississippi,
Georgia and South Carolina during the day.

Central and Southern Plains/Ohio Valley:
Moderately dense to locally thick smoke moved to the north and east from
fires burning over northern Nebraska and southern South Dakota. A slightly
larger area of thinner density smoke surrounded the thicker smoke. In
addition, a large mass of thin density smoke was analyzed over the Central
Plains which likely is partly from the Nebraska and South Dakota fires as
well as other fires burning over Kansas and Oklahoma. It is also possible
that the smoke from these fires extends farther to the east across the
Ohio Valley and to the south into southern Oklahoma and Texas, although
some other pollutants may be contributing to that aerosol as well.

Western US/Southwestern Canada:
Thin density smoke appears to be moving inland from the Pacific across
northern California, Oregon, and Washington, northern Idaho, western
Montana, and into southwestern Canada. This smoke is believed to be left
over from fires ongoing in Siberia.

Canada/Northern and Northeastern US:
Numerous large wildfires which are scattered across the region extending
from western to south central Canada continue to emit significant smoke. A
huge area of thin density smoke stretches from northern British Columbia
and the southern Yukon eastward and southeastward across south central
Canada to the northern Great Lakes region. The smoke then extends to the
east and northeast across southeastern Canada and northern Maine to the
Canadian Maritimes. Within this large area of smoke, moderately dense
to thick smoke was visible over western and south central Canada.

Southeastern Alaska/Western Canada:
More thin density smoke likely transported from the Siberian fires could
be seen across the Gulf of Alaska extending inland over southeastern
Alaska, northwestern British Columbia, and the southern portion of
the Yukon.

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.
