Abstract
In this paper, uncertainties in estimating anthropogenic aerosol indirect effects on warm clouds are explored using the recently developed Grid point Atmospheric Model (GAMIL) with prescribed aerosol fields. The anthropogenic aerosol indirect effect is calculated by the change in shortwave cloud forcing from preindustrial times to present-day. Simulations show anthropogenic aerosol indirect effect is not sensitive to two different physically-based droplet nucleation parameterizations. However, anthropogenic aerosol indirect effect is quite sensitive to the assumption on the subgrid vertical velocities, which are used to drive physicallybased droplet nucleation parameterization. Furthermore, sensitivity simulations indicate that aerosol influence on convective clouds, which is not considered in GAMIL model, might be an important contributor to anthropogenic aerosol indirect effect.
