DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1815Z July 30, 2015

SMOKE:
Alaska/Yukon Territory:
Mostly thin smoke from wildfires in central Alaska is seen beneath the
patchy clouds and is moving east towards the Yukon Territory. A small
area of embedded moderately dense smoke is also seen along the border
of Alaska and the Yukon Territory.

Western Canada/North Central US:
Several areas of light density smoke coming from the Siberian
and/or Alaskan fires are seen across portions of western and northern
Canada. Some smoke may have also been produced by a handful of wildfires
burning north of Great Slave Lake. Smoke extends southeast from Northwest
Territories across parts of British Columbia/Alberta/Saskatchewan/Manitoba
and southwest Ontario before extending further south/southeast into the
north central US. Smoke covers parts of the Dakotas, Nebraska, Iowa,
Missouri, Illinois, Minnesota, Wisconsin, Michigan, and Indiana as well
as Lake Huron and southeast Ontario.

California/Oregon/Idaho/Southwest Canada:
The wildfires in the Sierra Nevada and in northwest California are
producing expansive smoke plumes that are moving to the west/northwest
off the Sierras and then to the north. There are fairly large areas
of moderately dense smoke with most of these fires. The smoke extends
north across much of west and south central Oregon. Another area of
smoke likely attributable to the California wildfires is seen moving
northeast across north Idaho into southwest Canada.

East Canada/Northeast and Southeast US:
An extensive amount of aerosol is seen across much of Quebec extending
south/southeast ahead of a potent upper low and frontal boundary. This
aerosol is present along/ahead of the frontal boundary southward over the
entire Eastern Seaboard to the Southeast US states and coast. The most
optically thick area of the aerosol is seen over the Northeast US and
being pulled off the coast. Possible small areas of remnant Siberian smoke
are present within this aerosol over Massachusetts/New Hampshire and south
of Newfoundland. Otherwise the aerosol is thought to mostly be sulfates.

DUST:
Central US:
Saharan dust remains across the far western portion of the Gulf of Mexico
and extends north across a majority of Texas, southeast New Mexico,
and into Oklahoma.

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.
