Barra do Garças fire, 16 August 2022 Barra do Garças, Novo São Joaquim
The fire started on 16 August 2022 in Barra do Garças, Brazil, and satellites saw it burning for 24 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 44,194 hectares from heat detections, spread across 2 municipalities.
It is the 61th largest in Mato Grosso since 2016 (of 1996 with a page). Number 5 in Brazil in 2022, of 687.

The weather it burned in
It had gone more than two months without rain (1 mm or more) when it started.
This area had burned before
89% of the perimeter overlaps earlier fires recorded since 2016: 23,624 ha in 2016, 15,843 ha in 2017, 7,748 ha in 2018, 13,944 ha in 2019, 25,959 ha in 2020, 3,529 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 39,310 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
People and buildings inside the perimeter
GHSL 2020Inside the perimeter there were about 0.14 hectares of built-up land and about 100 residents (GHSL 2020, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned.

The smoke
CAMS · CopernicusOn 24 August 2022 the air beside the fire reached 135 µg/m³ of PM2.5. That day averaged 58: 3.9 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Barra do Garças fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 16 August 2022 to 8 September 2022 (24 days). The perimeter dates it from 18 August 2022 to 7 September 2022.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 44,194 hectares (441.9 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Barra do Garças (44,429 ha, 4.9 %); Novo São Joaquim (4 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 36.2 °C, humidity dropped to 6 % and gusts hit 48 km/h. The fire danger index (FWI) reached 61, class Extreme.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Brazil (geoBoundaries). It is not an official report.
Where to verify it
A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Does something look wrong on this page?
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 2 polygons grouped in this page.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 18 August 2022 to 7 September 2022. 1,865 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2020, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
Where this data comes from
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Creative Commons Attribution 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
