DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1705Z December 28, 2021

SMOKE:
No significant areas of smoke or dust were detected in satellite imagery
this morning due to heavy cloud cover over Canada and the lower 48.

SMOKE/AEROSOL:
Gulf of Mexico/Bay of Campeche/Mexico/Northwestern Central America/Pacific
Ocean South of Mexico and Central America, Texas...
The usual aerosol which has been seen fairly consistently for weeks
now was present again over portions of western, southern and eastern
Mexico, northwestern Central America, a area in the tropical eastern
Pacific south and west of the Mexico and Central America coastlines,
the southwestern Bay of Campeche, the western Gulf of Mexico, continuing
north into Texas. This aerosol was likely composed in part of atmospheric
pollutants including factory emissions and emissions from gas/oil flaring
and regional seasonal fire activity occurring in portions of Mexico and
northern Central America as well as Cuba. While it is virtually impossible
to distinguish the other atmospheric pollutants from smoke in satellite
imagery, it is believed that there is a greater likelihood for smoke to
be present along and off the southern coast of Mexico and northwestern
Central America over the relatively nearby portion of the Pacific, and
along and off the east coast of Mexico over the Bay of Campeche and the
far western Gulf of Mexico.

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:

ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO:

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.
