Tulsa Area Ozone Alert! Program
Our regional Ozone Alert! Program brings citizens, business, industry and government together to voluntarily reduce ozone-forming emissions on days vulnerable to high ground-level ozone.

1-hr Ground-Level Ozone Readings (ppb)
- West .040
- East .037
- Central .040
- North .041
- South .036
This Air Quality Index (AQI) reflects ONLY OZONE, corresponding to the EPA’s national standard for ground-level ozone and associated health concerns.
Today's High Ozone AQI is 0 at the North Monitor
0 – 49
50 – 99
100 – 149
150 – 200
The EPA’s Ozone Standard is Exceeded when the 8-hr Average is 0.071 ppm or greater
Today's high 8-hour average is .000 at the North Monitor.
Have we exceeded the 8-hour standard today? NO
Did we exceed yesterday? NO

Ozone is Good Up High but Bad Nearby.
Ozone is a gas found in the air we breathe and can be good or bad, depending where it occurs:
- Good ozone is present naturally in the Earth’s upper atmosphere—approximately 6 to 30 miles above the Earth’s surface. This natural ozone shields us from the sun’s harmful ultraviolet rays.
- Bad ozone forms near the ground when pollutants (emitted by sources such as cars, power plants, industrial boilers, refineries and chemical plants) react chemically in sunlight. Ozone pollution is more likely to form during warmer months. This is when the weather conditions normally needed to form ground-level ozone—lots of sun—occur.
