Air quality by ZIP

What zipradar shows

Pages show the current AQI category (Good, Moderate, Unhealthy for Sensitive Groups, Unhealthy, Very Unhealthy, Hazardous), the nearest reporting station, and historical averages.

Refresh cadence

Hourly real-time / daily historical. zipradar honors the regulator's publishing cadence; stale data is flagged rather than silently served.

Limitations

Rural ZIPs may not have a nearby monitoring station; zipradar then reports the closest available station with distance context.
