Where this data comes from

Perimeters come from GWIS (Copernicus, CC BY 4.0), rebuilt from heat detections, and municipal boundaries from geoBoundaries/Instituto Brasileiro de Geografia e Estatística (IBGE), OCHA ROLAC (Creative Commons Attribution 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). The area per municipality is computed by WorldFires by crossing both. The forecast is from Open-Meteo (CC BY 4.0).
