Rank
Why it ranks here
Cleaner than usual. The last 7 days averaged 18.5 µg/m³, well below its typical 42.9; rain or wind often clears the air for a while.
Chronic pollution. Its typical day over the past year was 42.9 µg/m³, 2.9× 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 January, February, December, averaging up to 96.0 µg/m³ against 14.2 in its cleanest month. Seasonal peaks usually come from heating, crop burning, fire or dust seasons.
Based on Kathmandu's own measurements; causes are the usual kinds for a pattern like this, not a confirmed source.
