Agricultural Fires in Florida

The air quality today was fair with moderate (Code-Yellow) levels sparsely scattered in the Mid-Atlantic, Southeast, and Southwest (top left). In Southern California and Arizona, air quality indices reached higher levels, Code-Orange.
Ozone levels remained fairly low today (top right).
Several light-density smoke plumes were observed over Florida. They are most likely associated with agricultural fires in the Lake Okeechobee region (bottom left). The smoke is being blown northward from their sources. In California, there wasa light-to-moderate density smoke plume due to a single wildfire in Inyo County. The smoke was travelling northeast-eastward.
Blowing dust was observed in western Nevada being transported for greater than 150 miles eastward (bottom right).

Low levels of PM 2.5 across the nation

PM levels were mostly good today, with only Code Yellow (Moderate) levels arising in the Northeast, the Northern Plains States, and parts of California (AirNow, top left). The elevated levels of PM 2.5 were partially due to smoke created by wildfires in the affected areas. However, there were only light plumes of smoke created, so the PM 2.5 levels were not impact very much. The light smoke coverage can be seen in NOAA's HMS smoke coverage, top right. The smoke was difficult to see because of heavy cloud coverage, as seen in NASA's MODIS Terra image, bottom left.

Seasonal Fires in the Great Plains

The air quality was reached Code-Yellow levels scattered across the U.S.; mainly in the Great Lakes region, in the Plains, and the Southwest (top left). The moderate levels seen in the Plains could be due to dust in the region (top right) and/or due to light density smoke plumes from seasonal fires in North central Texas and Central Oklahoma (bottom left). There were also several smoke plumes in florida near Lake Okeechobee and a thin plume in north central California.
Ozone levels remained fairly low today (bottom right).

Scattered light density smoke plumes

The air quality was fair throughout the day with the exception of moderate (Code-Yellow levels) along the Pacific coast and in the South along the Gulf coast (top left). Code-Orange levels of air quality along with some moderate ozone levels were seen in Southern California (top right). This could be associated with the thin density smoke plumes in Southern California and Arizona (bottom left). There were a few light density smoke plumes in Arkansas moving northward, in Georgia moving eastward, and plumes scattered throughout Texas, Oklahoma, and Florida. There was also an incident of dust along the Gulf coast which could be adding to the increased levels of particulate matter in the air (bottom right).

Southeast experiences smoke from small wildfires

PM 2.5 levels were high in various areas across the nation today, with Code Yellow (Moderate) levels being seen in the Pacific Northwest, the Pacific Southwest, the Rocky Mountain States, the Northeast, and the Plains States (AirNow, top left). The PM 2.5 in the Southeastern region was due to wildfires in this area, which spread light plumes of smoke across the region, as seen in NOAA's HMS map, top right. These light plumes of smoke were captured in NASA's MODIS Terra images, bottom left.

PM 2.5 levels heighten along the west coast

There were heavy amounts of PM 2.5 along the west coast, with Code Yellow (Moderate), Code Orange (Unsafe for Sensitive Groups), and Code Red (Unsafe) levels of PM 2.5 seen along the west coast, the Rocky Mountain States, and the Great lakes region, as seen in AirNow's PM map, left. However, the excess PM 2.5 was not due to smoke from wildfires, as there was only some smoke seen in the Southeast (NOAA, right). The rise in PM 2.5 was most likely due to people burning wood to keep warm in the winter months.

Fires in the Plain States and the Southeast

Overall, today was a great day in Air Quality news with minimal AOD reported throughout the nation. We did observe a large amount of fires in the Plain States and Southeast regions of the States. However, very low and minimal amounts of PM were produced from these fires. Smoke was seen in South Florida over Lake Okeechobee as seen in the HMS image below (left). AOD trajectories show low concentrations of aerosols from the Southern Plain States moving Northeast towards the Mid-Atlantic region of the nation (VIIRS CONUS, right).
