Iowa Air Quality Index

Current Air Quality Index (AQI) values for Iowa. AQI ranges from 0–500+, with higher values indicating worse air quality.

% Good days 90th percentile AQI Dominant Pollutant % of days unhealthy for sensitive groups Worst county Coverage %
69.9 57.9 PM2.5 0 Van Buren 14.1
% Good days
Percentage of monitored days rated “Good” (AQI 0-50).
90th percentile AQI
Weighted average of the air quality index at the 90th-percentile. This tells you what the typical AQI would be at for a bad day in Iowa. We use the 90th-percentile to eliminate extreme events, such as forest fires, that are not representative of typical conditions in the state.
Dominant Pollutant
The pollutant driving AQI on most days.
% of days unhealthy for sensitive groups
The percentage % of monitored days rated “Unhealthy for Sensitive Groups” (USG) or worse (AQI >100).
Worst County
The Iowa county with the highest percentage of USG+ days.
Coverage %
Percentage of counties in Iowa reporting AQI data.
