Wildfires in plains States slightly elevated PM 2.5

Air quality today was mostly good, with Code Yellow (Moderate) levels of PM 2.5 scattered across the nation. There were concentrations of this PM 2.5 seen in the Mid-Atlantic, the Rocky Mountain States, and the Plains States (AirNow, top left). This PM 2.5 was slightly affected by smoke in this area, although the smoke was mostly coming from wildfires in the southern Plains States and the Southeast (NOAA, top right). A small amount of the smoke in the northern Plains States could be seen in NASA's MODIS Terra images, bottom left, despite a large amount of cloud coverage in this area.
