Effective radiative forcing of anthropogenic aerosols in E3SM version 1: historical changes, causality, decomposition, and parameterization sensitivities

The effective radiative forcing of anthropogenic aerosols (ERF.sub.aer) is an important measure of the anthropogenic aerosol effects simulated by a global climate model. Here we analyze ERF.sub.aer simulated by the E3SM version 1 (E3SMv1) atmospheric model using both century-long free-running atmosp...

Zusammenfassung:	The effective radiative forcing of anthropogenic aerosols (ERF.sub.aer) is an important measure of the anthropogenic aerosol effects simulated by a global climate model. Here we analyze ERF.sub.aer simulated by the E3SM version 1 (E3SMv1) atmospheric model using both century-long free-running atmosphere-land simulations and short nudged simulations. We relate the simulated ERF.sub.aer to characteristics of the aerosol composition and optical properties, and we evaluate the relationships between key aerosol and cloud properties.
