Wildfires in midwest create rise in PM 2.5

PM 2.5 levels were somewhat high today, with small amounts of Code Red (Unsafe) being seen in the mid Plains States, along with some Code Orange (Unsafe for Sensitive Groups) in the same areas (Airnow, top left). This rise in PM 2.5 was most likely due to a large amount of wildfires in this area, and a large amount of smoke as a result (NOAA, top right). Some of the smoke in the Southeast could be seen amongst some cloud coverage in NASA's MODIS Terra images, bottom left. Ozone levels were mostly low, with some Code Yellow appearing in the Plains States and the Great lakes region (AirNow, bottom right).
