DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2345Z March 21, 2014


Unknown aerosols:
Mid-Atlantic:
A large swath of thin unknown aerosols stretches form NE OH across PA
into MD, DE before exiting the east coast out to about 70W.   The swath
is about 150km wide and has a very distinct northern boundary across PA
and the Delarware River outwash.   Generally, this area is moving ESE.

US West Coast into the Pacific:
Transported Asian aerosols, likely a mix of smoke, dust and pollution can
be seen behind the trof digging SE across OR and N CA attm.  A moderately
dense string of this aerosol is most distinct in a 25km wide band from
Eureka, CA, to the CA/OR/NV corner/border area.   Though thinner areas of
these aerosol precede this line as far south as the San Francisco Bay and
Lake Tahoe into SW ID.   This also connects back to the larger area still
well off shore along 43-45N out to about 150W.  There is a large pocket
of moderately dense aerosols ahead of the large polar cyclone moving east.

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.
