Looking at the NOAA HMS Smoke and Fire Product (top left), the small red dots indicate clumps of fires in the Southeast, the Northeast, and Canada. No significant plumes were seen, although the pockets of grey on the HMS illustrate small areas of smoke around some of these fires. Comparing this to the AOD image courtesy of MODIS Terra (top right), however, one can see there is little elevation in AOD because of these fires.
The EPA AIRNow combined AQI loop (bottom left) shows Code Yellow and even Code Orange AQIs in Texas and the Southeast. The high AQI for today was Houston-Galveston-Brazoria, TX (174), with the silver medal going to Lake Charles, LA (91) and the bronze going to Dallas-Forth Worth, TX (90). The aforementioned fires may have helped cause these elevated AQI values, and looking at the MODIS KML image (bottom right), one can see multiple fires that have been active in the past 6 hours in Texas, Louisiana, and Arkansas.
