India, October 2026
For 5 days, from 3 to 7 October 2026, 21 cities in India had PM2.5 at least twice their usual for the time of year. The worst reading was Ahmedabad, Gujarat, India: 94.5 µg/m³ on 7 October, about 3.1× its usual 30.2. Readings stopped after 7 October, when 489 monitors in India went silent, so this episode may have run longer.
Few fires were detected near these cities on those days. Spreads like this usually come from still weather trapping smoke from heating, traffic and industry, or from dust.

Bars: cities counted each day, coloured by their median level. Choose a day or press play; without JavaScript, the days link to that day's world ranking. Fires, seen Heat NASA satellites detected that day; bigger and glowing means more detections in the area. Farm burning and other fires count too, not only wildfires.Volcanic ash, warned A volcano with an ash warning for aircraft that day; shaded where forecasters saw the ash cloud.Under the cities, for each UTC day: fires NASA satellites detected, smoke NOAA analysts traced and volcanic ash warnings for aircraft. They show what was in the air, not that it caused the readings. Mapped for 9 of the 11 days shown.
Fires: NASA FIRMS (VIIRS). Traced smoke: NOAA Hazard Mapping System. Volcanic ash: aviation ash warnings (SIGMETs) via NOAA's Aviation Weather Center.

An episode is a run of days when many cities close to each other (four or more within 350 km on a day, 8 or more in all) each had a daily PM2.5 mean of at least 25 µg/m³ and at least 2 times their usual for that time of year. Found in our own measurements, not picked by hand. How we find episodes . Values are each city's daily mean of its own monitors; causes are the usual kinds for a pattern like this, not a confirmed source. Fire detections from NASA FIRMS; smoke maps from NOAA HMS.
