Most polluted cities in Silesia, Poland

5 measured cities, this year; 5 above the WHO annual guideline. Worst: Żywiec at 27.7 µg/m³, #340 in the world.

The 83 monitors run by EEA in Poland haven't reported since 30 Sept, 22:00 UTC. Cities that rely on them are missing from the 24-hour board and may drop from the longer ones; they return when the data does.

Estimated: cities without a monitor

Silesia 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.
