Abstract	Aerosols cycling through clouds affect particle morphological and chemical properties, thus modifying aerosol effects on cloud microphysics and climate. Previous studies have focused on aerosol processing in warm clouds via aqueous-phase reactions. Here we investigate the physical modifications of aerosols following processing within ice clouds using a unique laboratory setup that simulates ice cloud processes. The processed particles have a porous structure due to phase separation upon freezing, subsequent glass transition, and ice sublimation. Such modified aerosols can be better ice and cloud condensation nuclei and scatter less light. These changes have implications for aerosol–cloud interactions and optical properties of aerosols in the vicinity of clouds.
