DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z July 14, 2009

Northern California/Oregon/Washington:
Another surge of light to locally moderately dense aerosol is
moving onshore across northern California and much of Oregon and
Washington. Based on the latest SO2 imagery from the OMI satellite,
which does not depict SO2 over this area, it is felt that this is remnant
smoke from the massive fire outbreak in Alaska. A separate narrow patch
of thin remnant smoke is also seen stretching from near Monterey Bay to
Lake Tahoe.

Great Basin:
A couple of areas of blowing dust were seen being kicked up over Nevada
and Utah. One area was over eastern Nye county in Nevada and was moving
east into Utah. A second area was seen over the Great Salt Lake and
drifting to the south.

Western Ontario to the Mid Atlantic and New England:
A ribbon of aerosol was seen stretching from western Ontario across
western Lake Superior, into central Michigan, western Pennsylvania and
off the Atlantic coast from southern New Jersey. Based on the OMI data
noted above, it is felt that this plume is predominantly SO2, although
it is possible that some smoke is mixed in. OMI data can be viewed at

Alaska:
Remnant and recent smoke from the Alaskan fires was seen drifting to the
northwest and covering much of the northwest and central portion of the
state, mainly north of McGrath.

More information on the areas of smoke described above as well as others
can be found at the locations listed below.

THE FORMAT OF THIS TEXT PRODUCT IS BEING MODIFIED. IT WILL NO LONGER
DESCRIBE THE VARIOUS PLUMES THAT ARE ASSOCIATED WITH ACTIVE FIRES. THESE
PLUMES ARE DEPICTED IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE:

JPEG:   http://www.ssd.noaa.gov/PS/FIRE/hms.html
GIS:    http://www.firedetect.noaa.gov/viewer.htm
KML:    http://www.ssd.noaa.gov/PS/FIRE/kml.html

THIS TEXT PRODUCT WILL CONTINUE TO DESCRIBE SIGNIFICANT AREAS OF SMOKE
WHICH HAVE BECOME DETACHED FROM AND DRIFTED SOME DISTANCE AWAY FROM THE
SOURCE FIRE, TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. IT WILL ALSO
STILL INCLUDE DESCRIPTIONS OF BLOWING DUST.

ANY QUESTIONS OR COMMENTS REGARDING THESE CHANGES OR THE SMOKE TEXT
PRODUCT IN GENERAL SHOULD BE SENT TO SSDFireTeam@noaa.gov






 


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.
