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 major concentration of fires is in the Southeast region, specifically in Florida. Additionally, there are fires in the Midwest region, Texas and fires in the Northwest and Southwest regions. Although there is a large concentration of fires in Florida, there is little smoke being picked up by HMS. The next image shows the retrieved AOD image for the day, courtesy MODIS Terra. The image shows a slight increase in AOD in the Southeast and Texas regions, which most likely corresponds to some of the local fires. The code red in northern California may have also been enhanced by the local fire. Additionally, there is an increase in AOD in southern and central California.
The next image, courtesy EPA AIRNOW, shows the AQI values the country today from each station. Various sites in the Pacific Northwest reached code red values at the surface due to PM 2.5. This may be from local fires and residential wood fires. The next image, courtesy OMI NRT, shows the retrieved NO2 column for the troposphere. This image shows a large amount of NO2 in this same region as the elevated AQI values in the Northern Pacific Northwest region as well Central California. This enhancement in column NO2 shows a correlation with the increase in PM 2.5 at the surface.
