Reforestation-induced aerosol cooling effects divergently modulated by various types of biogeophysical feedback.

ABSTRACT: Reforestation and afforestation alter climate not only through biogeophysical processes such as changes in surface albedo, evapotranspiration and near-surface turbulence, but also by modifying emissions of biogenic volatile organic compounds (BVOCs) that drive biogenic secondary organic aerosol (BSOA) formation. Using an Earth system model coupled with an advanced aerosol module, we quantify how biogeophysical feedback from vegetation change influences BVOC emissions, BSOA burden and aerosol radiative effects under future land‑use scenarios. Our results reveal that biogeophysical feedback either amplifies or offsets BSOA cooling, depending on regional climate-vegetation interactions. In regions where reduced surface albedo dominates, increasing temperature and BVOC emissions enhance BSOA b
