Why it ranks here

Unusually bad for Dubai. The last 7 days averaged 73.5 µg/m³, about 2.1× its typical day (34.9). A jump like this usually has a short-lived cause: likely smoke from fires, dust, or stagnant weather trapping local emissions.

Likely fire smoke. On Sep 27, when Dubai averaged 102.0 µg/m³ (its typical day: 34.9), NASA satellites detected 83 fires within 300 km (2 within 100 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.

Chronic pollution. Its typical day over the past year was 34.9 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 February, July, August, September, October, November, averaging up to 47.5 µg/m³ against 22.5 in its cleanest month. Seasonal peaks usually come from heating, crop burning, fire or dust seasons.

Based on Dubai'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.
