Most polluted cities in Silesia, Poland

No city in Silesia, Poland has enough readings to rank for the last 24 hours.

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.

A city joins the 24-hour ranking with 18 hours of readings in the last 24; none here has that right now, so there is nothing to map or chart.

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.
