Short summary
Orbital remote sensing showed that the Cerrado was the second/first biome for the occurrence of hotspots and burned area (BA), which were higher in the dry season and in the savanna land use and are tending to decrease. Spatial analysis showed that values for the entire biome can hide patterns and that there is a 2- to 3-month lag between precipitation and hotspots/BA, while minimum VCI and maximum hotspots/BA occur in the same month. VCI indicates the susceptibility of vegetation to ignition.
