§ III — The Three Worst, Last 30 Days

Where the air is most consistently bad.

Three sensors with the highest mean PM2.5 over the last thirty days. The number on the left is the rolling mean against the WHO 5 µg/m³ annual guideline; the sparkline is the daily trace. Click any card to open the full historical record. The earlier silenced sensors live on the History page.
