AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Friday, September 22: Calm to light winds will inhibit dispersion, allowing pollutants to accumulate in the Columbus region. In addition, mostly sunny skies and warm temperatures will support ozone formation. Therefore, AQI levels will be Moderate. Saturday, September 23: An upper-level ridge will strengthen over central Ohio, limiting mixing in the atmosphere. In addition, light northeasterly winds will reduce pollutant dispersion, and temperatures in the upper-80s and sunny skies will enhance ozone formation. These conditions will lead to high-Moderate AQI levels. Sunday through Tuesday, the upper-level ridge will continue to limit vertical mixing in the atmosphere and produce sunny skies and warm temperatures, supporting ozone formation. Therefore, despite periods of moderate easterly to northeasterly winds aiding pollutant dispersion, AQI levels will be high-Moderate on all three days. Wednesday, slightly cooler temperatures will limit ozone formation. However, light westerly winds will limit dispersion, and pollutant carryover from the previous days will be high. As a result, AQI levels will be Moderate.
