Why it ranks here

Cleaner than usual. The last 7 days averaged 30.3 µg/m³, well below its typical 74.3; rain or wind often clears the air for a while.

Chronic pollution. Its typical day over the past year was 74.3 µg/m³, 5.0× the WHO 24-hour guideline, so it ranks high most of the time, not only during events.

Seasonal. Over the past year its worst months were November, December, averaging up to 232.5 µg/m³ against 31.9 in its cleanest month. Seasonal peaks usually come from heating, crop burning, fire or dust seasons.

Based on Dādri's own measurements; causes are the usual kinds for a pattern like this, not a confirmed source.

Hour by hour
