Effects of Precipitation and Fire on Land Surface Phenology in the Brazilian Savannas (Cerrado)

Fire and precipitation significantly influence land surface phenology (LSP) in the Brazilian Cerrado, with fire exerting a stronger impact on vegetation recovery metrics. A study analyzing Emas National Park using MODIS and HLS satellite data identified key LSP metrics—such as Amplitude (AMP), End of Season (EOS), and Seasonal Integrals (SSI)—that are highly responsive to both rainfall and fire disturbances. While precipitation primarily affects woodland areas, fire disrupts grasslands more severely, altering Base Level (BL) and recovery rates post-disturbance. The research highlights the importance of combining high-resolution satellite data to better understand vegetation dynamics in this globally significant ecosystem.
