Looking at the NOAA HMS Smoke and Fire Product (top left), the small red dots indicate a clump of fires over Texas and the Plains states as John mentioned yesterday. The HMS is not picking up any significant smoke plumes, however. Comparing this to the GAST EAST AOD animation to the right, this region has elevated AOD levels. But as mentioned, much of this is due to how GASP generates its values for AOD.
The EPA AIRNow combined AQI loop (bottom left) shows areas of moderate and unhealthy AQIs in the Plains states, Texas, and as always, Southern California. As of 18:30 UTC, the high AQI for the day occurred at Houston-Galveston-Brazoria, TX (202), although this seems to be an anomaly considering the next highest values in Texas are El Paso (106) and San Antonio (106). The fires in Texas and the Plains states most likely have affected these AQIs.
The images below are from Big Bend National Park, TX. The figure on the left is a webcam photo from today while the figure on the right is a comparison of clear and hazy days from the same location. Today's visibility range is 130 miles, so compared to the clear day's visibility of 243 miles, one can see that although the HMS does not pick up any plumes, the fires in Texas and the Plains states are affecting air quality.
