Most polluted cities in Estonia

4 measured cities, last 24 hours; 0 above the WHO 24-hour guideline. Worst: Tartu at 5.3 µg/m³, #975 in the world.

Estimated: cities without a monitor

Estonia 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	Band
Pärnu	≈ 5 µg/m³	Good
Viljandi	≈ 4 µg/m³	Good
Maardu	≈ 4 µg/m³	Good
