Abstract The component of the indirect aerosol effect related to changes in precipitation efficiency (the second indirect or Albrecht effect) is presently evaluated in climate models by taking the difference in net irradiance between a present-day and a preindustrial simulation using fixed sea surface temperatures (SSTs). This approach gives a “quasi forcing,” which differs from a pure forcing in that fields other than the initially perturbed quantity have been allowed to vary. It is routinely… Expand
Total aerosol effect: radiative forcing or radiative flux perturbation?
Abstract. Uncertainties in aerosol radiative forcings, especially those associated with clouds, contribute to a large extent to uncertainties in the total anthropogenic forcing. The interaction ofExpand
