Slight PM 2.5 across nation

Air quality today mostly stayed in the Code Yellow (Moderate) range of PM 2.5, with some Code Orange (Unsafe for Sensitive Groups) appearing on the border between Montana and Canada. The rest of the Code Yellow was concentrated in the southern Plains States, the Mississippi Valley, the Southeast, and southern California (AirNow, top left). The elevated PM 2.5 was mostly due to smoke from wildfires in the Southeast, which can be seen in NOAA's HMS map, top right. The smoke in this area could not really be seen, as most of the smoke was made of light plumes (NASA MODIS Terra, bottom left.) .

Wildfires in plains States slightly elevated PM 2.5

Air quality today was mostly good, with Code Yellow (Moderate) levels of PM 2.5 scattered across the nation. There were concentrations of this PM 2.5 seen in the Mid-Atlantic, the Rocky Mountain States, and the Plains States (AirNow, top left). This PM 2.5 was slightly affected by smoke in this area, although the smoke was mostly coming from wildfires in the southern Plains States and the Southeast (NOAA, top right). A small amount of the smoke in the northern Plains States could be seen in NASA's MODIS Terra images, bottom left, despite a large amount of cloud coverage in this area.

Light smoke spreads in Southeast

Air quality today was mostly good, with only Code Yellow (Moderate) levels of PM 2.5 appearing in the Rocky Mountain States, the Southeast, and California (AirNow, top left). This elevated amount of PM 2.5 in the Southeast was partially due to the smoke in this area, which can be seen in NOAA's HMS map, top right. The plumes of smoke in this area were mostly light plumes, which is why the PM 2.5 levels in this area were not too high. The smoke in this area was somewhat captured in NASA's MODIS Terra images, despite heavy cloud coverage in the area (NASA, bottom left).

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).
