Most polluted cities in New Aquitaine, France

9 measured cities, this year; 9 above the WHO annual guideline. Worst: Bordeaux at 9.0 µg/m³, #968 in the world.

Estimated: cities without a monitor

New Aquitaine 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.
