The first image below, courtesy NOAA HMS, shows the fire locations across the United States. The red dots correspond to active fires, and the grey areas are plumes. The largest plumes are continuously stretching from the Northwest to the Northeast regions of the country. Canada has also had many fires and the smoke from these continues to affect air quality in the U.S. The next animation, courtesy GASP EAST, shows the AOD loop for the country today. You can see that most of these raised values correspond to the fires and smoke debris throughout the nation. Some of the increased values in the Southwest in the first few frames of the loop may also be do to blowing dust and sand, as forecasted by NOAA as well.
The first image below shows the forecasted EPA AIRNOW AQI values for the Great Lakes and Mississippi Valley regions. There were some code reds forecasted due to possible ozone increase, but nothing reached above code orange. The image beside that, shows the the NOAA forecasted ozone values ending at 7:00 EST. Some of these cities continue to have increased values of ozone, even into the evening.
The image below shows the CALIPSO lidar 532 Total Attenuated Backscatter image with an overpass over the Northeast region, emphasizing the PM 2.5 amounts and altitudes. There are large amounts of aerosols in the first few kilometers that are due to the wildfires in those coordinates. There is also a light layer ~10 km (-61.22, -97.37) that may be a thin cloud or a light layer or smoke aloft.
