Good air quality was experienced in most of the Nation. AirNow reported moderate PM2.5 levels in mostly in the southern Mississippi Valley, the Great Lakes region and in California (top left). As for Ozone, moderate levels were reached in the same regions (except the Great Lakes) during the afternoon (top right). In terms of fires, HMS reported a plume of light-density smoke visible moving SE from the SW corridor of Manitoba crossing the border into North Dakota extending into South Dakota. This remnant smoke originates from the wildfires burning just south of Great Slave Lake (middle left). Besides the smoke detected by HMS, AOD animation retrieved by MODIS only shows light aerosol loading in the areas aforementioned (middle right). Finally, Monterrey aerosol Modeling indicates a long belt of high sulfate concentration extending form northeast Canada to the Mississippi Valley. Dust patches are also modeled in different states (bottom).
