SmogRank / World / North America / Mexico / Yucatán
Most polluted cities in Yucatán, Mexico
No city in Yucatán, Mexico has enough readings to rank so far this year.
A city joins this ranking with enough days of readings so far this year; none here has that right now, so there is nothing to map or chart.

Estimated: cities without a monitor
Yucatán 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.
