DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0230Z August 7, 2015

SMOKE
Alaska:
An area of light to moderate density remnant smoke was observed from
central Alaska heading eastward into Yukon. Cloud cover obscured the full
extent of this area of remnant smoke in southern Alaska, eastern Alaska
and Yukon. Wildfires in central Alaska have contributed to this area of
smoke and are emitting moderate to heavy density smoke plumes moving ESE.

Northern Canada:
An expansive area of light to moderate density smoke was visible across
Northern Canada spanning from the Northwest Territories into Nunavut,
Hudson Bay, northwestern Quebec, Baffin Island, the North Atlantic Ocean
and possibly into Greenland although the smoke was more diffuse farther
east making it difficult to delineate the full extent of this area of
smoke in the North Atlantic Ocean. Wildfires in northern Alberta and
the central portions of the Northwest Territories continue to provide
moderate to heavy density smoke plumes tracking northwards contributing
to this area of smoke.

Pacific Northwest/Northern Plains:
A band of light to moderate remnant smoke is seen from off the coast of
northern California, southern Oregon, northern Nevada, southern Idaho,
Wyoming, the Dakotas and northwestern Nebraska. A low pressure system is
drawing this band of remnant smoke north into southern Saskatchewan.
In northern California and southwest Oregon wildfires continue to
emit heavy density smoke moving to the northwest off the coast adding
additional smoke to the band of remnant smoke. Clouds over central
California and Nevada which are moving towards the northeast began to
obscure this area of smoke.

AEROSOLS
Gulf of Mexico/Atlantic Ocean/Southern US/Great Lakes Region:
Areas of Saharan dust are visible throughout the Caribbean westward
across the Gulf of Mexico and into Texas, the Gulf coast states and
the southeastern US but clouds began to obscure this aerosol in the
southeast. The dust was also visible passing from the eastern Gulf of
Mexico over Florida and NE into the Atlantic Ocean and all along the
eastern seaboard. Sulfates are likely present among the Saharan dust
in the southern Plains, and the southeastern US. In between cloud cover
over the Great Lakes region as far east as New York an aerosol composed
of Sulfates, Saharan dust and possibly smoke is present

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.
