Light smoke spreads in Southeast

Air quality today was mostly good, with only Code Yellow (Moderate) levels of PM 2.5 appearing in the Rocky Mountain States, the Southeast, and California (AirNow, top left). This elevated amount of PM 2.5 in the Southeast was partially due to the smoke in this area, which can be seen in NOAA's HMS map, top right. The plumes of smoke in this area were mostly light plumes, which is why the PM 2.5 levels in this area were not too high. The smoke in this area was somewhat captured in NASA's MODIS Terra images, despite heavy cloud coverage in the area (NASA, bottom left).
