Estimated: cities without a monitor
Dalarna 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.
| City | 7-day estimate |
|---|---|
| Borlänge | ≈ 7 µg/m³ |
| Falun | ≈ 7 µg/m³ |
| Ludvika | ≈ 7 µg/m³ |
