Most polluted cities in South Moravian, Czechia

No city in South Moravian, Czechia has enough readings to rank for the last 30 days.

47 monitors in Czechia stopped reporting on 6 Oct, 12:00 local time. Cities that rely on them are missing from the 24-hour board and may drop from the longer ones; that isn't clean air, and they return when the data does.

A city joins this ranking with enough days of readings over the last 30 days; none here has that right now, so there is nothing to map or chart.

Estimated: cities without a monitor

South Moravian 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.
