Southern Brazil, 30 August to 5 September 2024
For 7 days, from 30 August to 5 September 2024, 31 cities in Brazil had PM2.5 at least twice their usual for the time of year. The worst reading was Ribeirão Preto, São Paulo, Brazil: 105.5 µg/m³ on 3 September, about 5.7× its usual 18.6. Ended 5 September.
Likely smoke from fires Fires were detected within 300 km of the city on 49% of the counted city-days. Satellites see crop, field and forest fires alike, so this doesn't say which burned.

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.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 11 of the 13 days shown.
Fires: NASA FIRMS (VIIRS). Traced smoke: NOAA Hazard Mapping System. Volcanic ash: aviation ash warnings (SIGMETs) via NOAA's Aviation Weather Center.

Daily means in µg/m³, over the days each city counted in this episode. Highest: its highest of those days. Usual: the city's median for the time of year of that day (its days within 21 days of the date, every year, leaving out the week around it). Above usual: its highest day against that, with a usual under 5 µg/m³ taken as 5.

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. Dust: contains modified Copernicus Atmosphere Monitoring Service information 2024. Neither the European Commission nor ECMWF is responsible for any use that may be made of the Copernicus information or data it contains.
