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. There are large plumes and a high concentration of fires in the Pacific Northwest and Rocky Mountain regions. Most of this smoke has been transported from the northern Canada fires. These plumes are mostly stretching eastward. The second image below, courtesy of GASP EAST, shows the retrieved AOD for the country today. You can see that most of these raised values correspond to more optically thick areas, which correspond to the fires and smoke debris throughout the nation. Specifically, the large concentration of smoke in the Rocky Mountain region show up clearly in the AOD image. You can see slightly raised values in the Great Lakes region due to sulfate aerosols (courtesy NRL NAAPS) and light smoke layers. (CALIPSO image not available at this time, but NOAA HMS picked it up also).
The first and second images, courtesy EPA AIRNOW, show the Pacific Northwest/Rocky Mtn AQI animation for the highest actual AQI for the country which is in Auburn, CA (near Sacramento) for Pm 2.5. This is mostly due to the American wildfire due east of Auburn that has a thick plume stretching over it. Additionally, sunny skies and temperatures in the low- to mid-90s have enhanced ozone formation in the Sacramento region. There are other various cities in the Pacific Northwest that have experienced a code red due to Pm such as Ketchum, ID (196, ancillary monitor ), Roseville-Rocklin, CA (AQI-161), Western Nevada County, CA (121), and Salmon, ID (152). The next image is of the AQI values in Idaho. You can see that the smoke plumes in the center of the country are being advected eastwards and may be aloft, so air quality in the Mid-Atlantic may be affected in the coming days as it reaches the surface.
