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 not any noticeable plumes to report at this time. There are scattered fires across the western portion of the country and a small concentration of fires in Florida. The image below, courtesy GASP MODIS (Terra satellite), shows the AOD image 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. There are raised values in the center of the country (which may be due to nitrates) and Florida.
The first image below, courtesy EPA AIRNOW, shows the loop of AQI values for the Pacific Southwest. There are moderate and USG values that are due to PM 2.5 in the area. This may be similar to the hazy conditions observed by Ray over the weekend in the San Joaquin Valley, CA. This appears to be heaviest in the Hanford and Bakersfield areas.
There are also elevated concentrations of NO2 below in the OMI Tropospheric NRT measurement. This shows that the major component of this particulate matter in this region is nitrate aerosols. This may also be the reason for the large AOD values in the center of the country in the GASP MODIS image above.
