Why it ranks here

Chronic pollution. Its typical day over the past year was 40.8 µg/m³, 2.7× 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 January, December, averaging up to 74.1 µg/m³ against 33.3 in its cleanest month. Seasonal peaks usually come from heating, crop burning, fire or dust seasons.

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