Why it ranks here

Cleaner than usual. The last 7 days averaged 17.4 µg/m³, well below its typical 34.4; rain or wind often clears the air for a while.

Chronic pollution. Its typical day over the past year was 34.4 µg/m³, 2.3× 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 March, November, averaging up to 108.4 µg/m³ against 15.1 in its cleanest month. Seasonal peaks usually come from heating, crop burning, fire or dust seasons.

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