Why it ranks here

Likely fire smoke. On Sep 30, when Birkirkara averaged 15.8 µg/m³, NASA satellites detected 53 fires within 300 km. Smoke from those fires is a likely contributor; we don't check which way the wind blew, and mapped smoke can be high above the ground.

Based on Birkirkara's own measurements, with fire detections from NASA FIRMS and smoke maps from NOAA HMS; causes are the usual kinds for a pattern like this, not a confirmed source.
