Air Quality Details (2024–2025)
The Air Quality Index (AQI) measures how clean or polluted the air is. A lower AQI means cleaner air. Main pollutants include particulate matter like PM2.5, ozone, and others regulated by EPA standards.
Air quality data sourced from OpenAQ, aggregating official monitoring stations.
| Yearly Average AQI | National Average AQI | Good Days | Moderate Days | Unhealthy Days | Worst Day AQI | Top Pollutant |
|---|---|---|---|---|---|---|
| 31.5 | 41.4 | 304 | 50 | 0 | 80 (on 3/17/2025) | PM2.5 |
Monthly AQI Trend
Monthly average AQI values over the past year. Lower values are better. Peaks may indicate pollution events.
