DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0330Z September 30, 2014

SMOKE:
Central U.S/Canada:
A large area of light-density smoke continued to be seen throughout the
central US and Great Lakes region. The smoke stretched from north Texas
northward to the Nebraska/South Dakota border and then northeastward
along a frontal boundary across the Midwest states to southern
Michigan. Numerous agricultural burns that have been taking place in
the Southern Plains and along the Lower Mississippi River Valley the
past few days are the cause of this area of remnant smoke and additional
fires were present in those areas today.

Gulf of Alaska to the Pacific Northwest Coastline:
An expansive area of aerosol is present off the western coast of
North America stretching from the Gulf of Alaska southeastward to the
Oregon/Washington coasts. Aerosol models indicate that this could be
smoke from Asia that has made its way across the Northern Pacific.
In addition, within the Gulf of Alaska another event is adding a different
aerosol to the mix. Re-suspended volcanic ash from the Novarupta volcanic
eruption of 1912 is seen moving south and southeast from the Alaska
Peninsula across Kodiak Island and over the Gulf of Alaska. Strong
northerly winds are the cause of this elevated aerosol event.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS
OF 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.
