Temperatures create ozone in Pacific Southwest

Air quality today ranged from Code Yellow (moderate) levels to Code Purple (Very Unhealthy) levels (AirNow, top left). The Code Orange (Unsafe for Sensitive Groups), Code Red (Unhealthy), and Code Purple levels of PM 2.5 were mostly seen in the Pacific Southwest and the Rocky Mountain States. Code Yellow levels, however, were more widespread, appearing in the Pacific Southwest, the Mississippi Valley, the Plains States, and the Southeast. The PM 2.5 in the Plains States region was mostly due to smoke from wildfires in this area, as seen in NOAA's HMS, map, top right. Ozone levels in the Plains States, the Pacific Southwest, and the Rocky Mountain States reached Code Yellow levels, with some Code Red levels in California and Arizona (weather.gov, bottom left). The elevated levels of Ozone in these areas were most likely due to increased temperatures in this area, as seen in weather.gov's temperature map, bottom right. The temperatures in this area reached highs of nineties and hundreds, which most likely contributed to the high levels of ozone today.
