Stagnant Summer Days Build Up Ozone

Ever wonder why some days are Air Quality Alert days and others aren’t?  Air Quality Alerts during Kentuckiana summers are often for the pollutant ozone.

Ozone is more readily formed on warm, sunny days when the air is stagnant. Conversely, ozone production is more limited when it is cloudy, cool, rainy, or windy. Air quality forecasters  provide calculated predictions of the air quality. When there’s a good chance ozone (or particulate matter) will reach 100 or higher on the Air Quality Index, an Air Quality Alert is issued for our area.

You can help clean the air during Air Quality Alerts by driving less and putting off mowing with gasoline-powered lawn equipment.
