About Air Quality in Iowa
Air quality in Iowa is monitored by the US EPA AirNow network using certified government sensors. Data is updated hourly and reported using the US Air Quality Index (AQI) — a 0–500 scale where lower is better.
The AQI is calculated from six key pollutants: PM2.5, PM10, ground-level ozone, nitrogen dioxide, sulfur dioxide, and carbon monoxide. Learn how AQI is calculated →
