Short summary

The Brazilian Regional Atmospheric Modeling System (BRAMS) was enhanced with crown fire spread in the surface fire spread (SFIRE) module and dynamic smoke emissions, enabling coupled fire–atmosphere–radiation simulations. Applied to the 2017 Sertã wildfire, the results show qualitative agreement with MERRA-2 aerosol optical depth (AOD), capturing the main plume structure, timing, and smoke-driven radiative effects, as well as interactions affecting atmospheric instability and inversion layers.
