Rank, worst first

24 hours–not enough data
7 days#103of 2,330, at 25.7 µg/m³
30 days#17of 2,324, at 51.8 µg/m³
This year#12of 2,173, at 66.4 µg/m³

Why it ranks here

Cleaner than usual. The last 7 days averaged 25.7 µg/m³, well below its typical 70.5; rain or wind often clears the air for a while.
Chronic pollution. Its typical day over the past year was 70.5 µg/m³, 4.7× 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 255.0 µg/m³ against 40.6 in its cleanest month. Seasonal peaks usually come from heating, crop burning, fire or dust seasons.

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