Estimated: cities without a monitor
Maule Region cities we can't measure, with model estimates for the last 7 days. Listed by population, not ranked: estimates aren't precise enough to rank. Model estimates from the Copernicus Atmosphere Monitoring Service (CAMS), adjusted to measured cities nearby where there are any. Adjusted, a single day lands within ×1.5 of what a monitor would read about two times in three; unadjusted, it can be off by half or double. Treat them as a guide, not a measurement.

|---|---|
| Constitución | ≈ 8 µg/m³ |
| Molina | ≈ 16 µg/m³ |
| San Javier | ≈ 12 µg/m³ |
