DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z May 25, 2010

Central US/Great Lakes Region/South Central and Southeastern Canada:
A large mass of aerosol was observed under the large upper level high
pressure ridge axis extending from the middle Ohio Valley and middle
Mississippi Valley regions northward through the upper Mississippi
Valley and Great Lakes region. The aerosol then extends northeastward
into south central Canada and eventually eastward across Southeastern
Canada. It is not known if the aerosol is composed of any leftover smoke.

Gulf of Mexico:
A distinct large patch of aerosol was visible through the day across a
good portion of the central and eastern Gulf of Mexico. Some smoke may
be contributing to this aerosol, though it is not known how much smoke
is present there.

Central US:
A swath of aerosol, which is likely partially composed of smoke and
blowing dust, stretches from southern Texas northward to the Central
and Northern Plains. Smoke from the seasonal fires burning in Mexico
and Central America may have been drawn northward and could be present
in these areas. Additionally, large fires in southern New Mexico and
northern New Mexico (near the Colorado border) are producing large smoke
plumes which are moving in a northeastward direction and are merging
with the band of aerosol over the Plains. Finally, streaks of blowing
dust originating from sources in Colorado were visible this afternoon
moving rapidly to the east and northeast toward the Central Plains of
Kansas and Nebraska.

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.
