DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z August 29, 2010

Lower Mississippi Valley/Eastern Texas/South Central Canada/Great
Lakes States:
A thin to moderately dense area of smoke extends from southeastern
Texas north-northeastward across the Mississippi Valley, Ohio Valley,
Great Lakes and into south-central Canada.  Moderately-dense smoke
is mostly concentrated over potions of eastern and northern Missouri,
Illinois, eastern Iowa, western Indiana and western Michigan.  Smoke is
attributed to numerous agricultural fires that were analyzed yesterday
across eastern TX and lower Mississippi Valley as well as from wildfires
burning in the northern Rockies.  Smoke likely extends further south
and east across lower portions of the Mississippi Valley based on
yesterday's analysis, however dense cloud cover from a low pressure
system is obscuring the ability to detect smoke in this area.  It is also
difficult to determine how far east the area of smoke extends because in
GOES-EAST it is very difficult to detect, while in GOES-WEST with the
more optimal early-morning sun angle the smoke shows up very clearly.
However the limiting factor with GOES-WEST is that it does not provide
imagery far enough east to determine the eastern extent of the smoke.
Based on satellite imagery from this morning smoke is seen as far east
as western and upstate New York, but it is likely that the eastern extent
is farther to the east than can be observed in morning satellite imagery.

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.osdpd.noaa.gov/ml/land/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.
