Most polluted cities in Delhi, India

6 measured cities, this year; 6 above the WHO annual guideline. Worst: Bawāna at 81.0 µg/m³, #32 in the world.

The 457 monitors run by CPCB in India haven't reported for more than two days. 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

Delhi 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.
