Moderate levels of PM 2.5 and Ozone

PM 2.5 levels today stayed at Code Yellow (Moderate) levels today, spreading across the Southern Plains States, the Mississippi Valley, the Great Lakes region, and the Mid-Atlantic, along with trace amounts in California (AirNow, top left). The rise in air quality along the East coast was most likely due to smoke from wildfires in the Southeast. The wildfires, along with the smoke from these fires, can be seen in NOAA's HMS map, top right. Light plumes of this smoke could be seen in NASA's MODIS Terra images over the Southeastern region. Ozone levels, much like the PM 2.5 levels, stayed around Code Yellow levels. Ozone was mostly spread around the East coast, the Northern Plains States, and the Pacific Southwest.
