Today, moderate air quality continued to blanket the majority of the Eastern United States. This moderate air quality persisted throughout the day, with a few patches of Code Orange (Unhealthy for Sensitive Groups) throughout the blanket of moderate air quality. In the west, continuing wild fires in northern and central California resulted in large patches of hazardous, very unhealthy, and unhealthy air quality.
The HMS image on the right shows smoke from the California fires trailing to the northeast, a large mass of fires in the plains with an associated smoke plume and fires in the Mississippi River Valley. A smoke plume was reported over the center of the country. The GASP image, at the bottom, shows high air optical depth, indicating smoke or some other matter in the atmosphere over a large portion of the western part of the nation.
