DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0132Z September 29, 2023
SMOKE: Central and Eastern Canada/Northern Plains/Northern CONUS/North Atlantic/Greenland/Europe… Wildfires across western Canada produced a large far-stretch area of moderate smoke that extends from Hudson Bay eastward across the North Atlantic and encroaching upon the European continent. Within this area, a patch of thick density smoke was seen extending from southeast Canada through the North Atlantic Ocean. It is likely more smoke is present over Nunavut and the eastern Canadian Archipelago, but cloud cover is obscured the area precluding further analysis in the region. Eastern Pacific/Mexico/Gulf of Mexico/Mississippi Valley/Southeastern CONUS… An area of light to moderate density smoke from agricultural burning across the Mississippi Valley, southern Plains, and southeastern CONUS over the past few days, was seen blanketing an area from the southern Plains through Mississippi Valley and southward along the western Gulf of Mexico. Within this region moderate smoke was seen over the Mississippi Valley, where the heavy agricultural burning was located. Smoke then crosses the Isthmus of Tehuantepec, where some emissions from gas flaring were observed and become incorporated into the layer before moving out over the Pacific. Another layer of mixed smoke and other aerosol was observed blanketing much of the Eastern Pacific. The exact sources of this aerosol layer are uncertain. Eglin 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: JPEG map: https://www.ospo.noaa.gov/data/land/fire/currenthms.jpg Smoke data: https://satepsanone.nesdis.noaa.gov/pub/FIRE/web/HMS/Smoke_Polygons Fire data: https://satepsanone.nesdis.noaa.gov/pub/FIRE/web/HMS/Fire_Points ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO: SSDFireTeam@noaa.gov
