Outdoor
Consider keeping outdoor activity lighter until conditions improve.
Why: AQI or pollutant levels are elevated, so this guidance is more cautious.

Practical guidance
Running
A lighter indoor option may be more comfortable today.
Why: Air quality indicators are elevated, so the running guidance is more cautious.
Ventilation
Consider waiting before longer ventilation.
Why: PM2.5, PM10, NO2 or ozone is elevated, so longer ventilation may bring more outdoor pollution indoors.

What affects air quality in Atlanta
Atlanta Regional Commission's ozone conformity analysis models motor-vehicle NOx and VOC emissions for the Atlanta maintenance areas and compares the results with approved motor vehicle emissions budgets; the report explains that NOx and VOC combine in sunlight to form ozone.
This describes regional transportation-conformity modeling and approved budget comparisons, not current concentrations, source dominance, conditions on a particular road, or this site's current-data provenance.
Local monitoring and context
Georgia EPD's 2026 plan documents the United Avenue site in Atlanta (AQS 13-121-0055) as representing the Atlanta-Sandy Springs-Alpharetta MSA and monitoring ozone and PM2.5; its Georgia Tech near-road site (AQS 13-121-0056) monitors NO2/NO/NOx, CO, PM2.5 and black carbon.
This is monitoring-network context from the draft 2026 plan; site parameters and plans can change, individual monitors are not citywide, and the network is not this site's current-data provider.
City air quality FAQ
How should I read the AQI for Atlanta?
US AQI condenses air quality into one value. On this page, it helps you quickly judge whether conditions look good, moderate or more polluted than usual.
Is the air quality good for going outside?
Check the outdoor and running cards first. They combine AQI, particles, ozone, weather and other factors that can affect outdoor comfort.
Should I ventilate right now?
The ventilation card considers AQI and pollutants such as particles, nitrogen dioxide and ozone. If values are elevated, a shorter opening or a later moment may be better.
Why can air quality change during the day?
Weather, emissions, ozone formation, particles and air flow can shift local conditions, so the next hours can differ from the current reading.

Current data
This page uses US AQI.
Current and hourly air-quality values are CAMS-based model estimates, not measurements from a local monitoring station. They may not reflect street-level conditions.

Report pages 7-8 explain that NOx and VOC form ozone and that the ozone conformity analysis uses approved motor vehicle emission budgets; page 28 says modeled NOx and VOC results are compared with the applicable budgets.
Applicability: Official active regional conformity report, latest revision February 2024; it supports regional modeling and budget-comparison context, not current air quality or source dominance.
