Short summary
We investigate stratospheric aerosol geoengineering with solid particle injection by modeling the fractal structure of alumina aerosols and their interaction with background sulfate. We analyze the efficacy (W m^-2 of radiative forcing per megaton of injection) and risks (ozone loss, s) for both alumina and diamond particles as a function of injected monomer radius, finding 240nm alumina and 160nm diamond optimal. We discuss the limitations of our 2-D model study and associated uncertainties.
