Uncertainties in aerosol direct and indirect effects attributed to uncertainties in convective transport parameterizations

► The sensitivity of aerosol effects to deep convective entrainment has been explored. ► More entrainment leads to increased aerosol load near sources & decreases elsewhere. ► Particularly for absorbing aerosol, as source regions have frequent deep convection. ► Response: more surface solar radiation in remote regions. Opposite for source regions. ► Aerosol indirect effect increases if aerosol increases coincide with liquid clouds.
