About This Data

Data Sources

Historical air quality mapping and scoring are based completely on official U.S. Environmental Protection Agency (EPA) AirNow API data. 5-day AQI forecasts are provided by WAQI.

Methodology

Our Clean Air Score (0-100) is a proprietary algorithm that weighs multiple factors:

Annual PM2.5 averages (40%)
Frequency of unhealthy days (25%)
5-year pollution trends (20%)
Seasonal variability and extreme events (15%)

Updates & Accuracy

Real-time data is updated hourly. Historical aggregate scores are recalculated monthly to reflect the latest trends. While we strive for accuracy, sensor maintenance and local conditions can affect individual readings.

Practical Advice

When AQI > 100: Sensitive groups (children, elderly, asthmatics) should limit prolonged outdoor exertion.
When AQI > 150: Everyone should avoid outdoor exercise and keep windows closed.
