Ozone levels increase with temperature spikes

PM 2.5 levels were very low today, with only Code Yellow (Moderate) levels being seen in the southern Plains States and the Pacific Southwest, along with some in the Mississippi Valley (AirNow, top left). This small amount of PM 2.5 was somewhat due to light plumes of smoke in the South, as seen in NOAA's HMS map, top right. Ozone levels, however, were very widespread, and rose up to Code Orange (Unsafe for Sensitive Groups) levels. The Code Yellow levels were in the Pacific Southwest, the Rocky Mountain States, the Plains States, and the Great lakes region. The Code Orange was in the Great lakes region and the Pacific Southwest (AirNow, bottom left). These elevated levels of PM 2.5 were somewhat due to increased temperatures in this area, as shown in NOAA's temperature map, bottom right. The temperatures in this area had highs in the nineties and hundreds, which most likely contributed to ozone production in these areas.

it is known that ozone concentration keeps a relation with heat. The point is how can we help to decrease the temperature?
