Calculic's European AQI calculator assesses the value using your population group and planned activity intensity.

MORPC's Franklin County neighborhood program combines sensor data with a model that distinguishes background, area, traffic, point and uncategorized sources of particle pollution.
These are the project's modeling categories, not a measured source ranking, proof of an individual source's contribution or a current citywide reading.
MORPC distinguishes Ohio EPA's regulatory monitors used for regional forecasting from its complementary Franklin County neighborhood monitoring; the CLEAN program uses PurpleAir sensors to monitor PM2.5.
The neighborhood sensors are supplementary low-cost instruments, not regulatory reference monitors or the provider of this page's current data.
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.
Check the outdoor and running cards first. They combine AQI, particles, ozone, weather and other factors that can affect outdoor comfort.
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.
Weather, emissions, ozone formation, particles and air flow can shift local conditions, so the next hours can differ from the current reading.
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.
City Air Quality selects the active data package, combines weather and air-quality data, chooses the current or latest usable model value, and formats it for this page.
The latest update is older than expected, so this page is showing an estimate for the current hour.
Detailed metrics and guidance use the latest available detailed data.
Each local statement is linked to a checked primary-authority source. A source check is editorial provenance and does not describe current-data freshness.
Local sources support the background claims below; they are not the source of the current data shown above unless explicitly stated otherwise.
