About This Data
Data Sources
Historical scores use stored EPA-derived city records. Current observations are requested separately and may use monitoring or modelled regional data. Inspect each report’s source and reporting period.
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
Historical year labels describe the available observations, not the site edition year. Some locations inherit a nearby city’s historical score and are labelled as regional references. Current readings may be unavailable or delayed.
