PM 2.5 and Ozone levels mostly low

PM 2.5 levels stayed around Code Yellow (Moderate) levels in the Mid-Atlantic and the Great Lakes Region (AirNow, top left). There were very low levels of smoke today, with only some light plumes of smoke appearing in the mid Plains States and the Southeast, so the smoke may have slightly affected the PM 2.5 levels in this area (NOAA, top right). Some light plumes of smoke can be seen in NASA's MODIS Terra images, bottom left. Ozone levels were very low as well, with only some small amount of Code Yellow appearing in the Rocky Mountain States and California.
