Wildfires are a complex and underexplored aspect of the Earth system, significantly affecting climate, as they emit greenhouse gases and aerosols that alter the Earth’s radiative balance. This study utilizes the EC-Earth3 Earth System Model to investigate how interannual variability in biomass burning emissions influences variability in total aerosol optical depth (AOD), as well as carbon monoxide (CO) and ozone (O3) tropospheric columns. We demonstrate that fluctuations in biomass burning emissions impact AOD, CO, and O3 variability at regional and global scales, emphasizing the need for improved understanding of wildfires and their climate effects.
