Low levels of ozone and PM 2.5 across th nation

Air quality today was very good, with only Code Yellow (Moderate) levels of PM 2.5 being seen in the Southern Plains States, the Rocky Mountain States, and the Pacific Southwest, with some Code Orange (Unsafe for Sensitive Groups) being seen in California (AirNow, top left). This low spread of PM 2.5 was somewhat due to low levels of smoke being seen across the nation, as seen in HMS' smoke map, top right. Ozone levels were also very good, with only small amount of Code Yellow being seen in the Pacific Southwest and the Rocky Mountain States (, bottom left).
