英文摘要	Aerosols can enhance ecosystem productivity by increasing diffuse radiation. Such diffuse fertilization effects (DFEs) vary among different aerosol compositions and sky conditions. Here, we apply a suite of chemical, radiation, and vegetation models in combination with ground- and satellite-based measurements to assess the impacts of natural and anthropogenic aerosol species on gross primary productivity (GPP) through DFE from 2001-2014. Globally, aerosols enhance GPP by 8.9 Pg C yr(-1) under clear-sky conditions but only 0.95 PgC yr(-1) under all-sky conditions. Anthropogenic aerosols account for 41% of the total GPP enhancement, though they contribute only 25% to the increment of diffuse radiation. Sulfate/nitrate aerosols from anthropogenic sources make dominant contributions of 33% (36 %) to aerosol DFE under all-sky (clear-sky) conditions, followed by the fraction of 18% (22 %) by organic carbon aerosols from natural sources. In contrast to other species, black carbon aerosols reduce global GPP by 0.28 (0.12) PgC yr(-1) under all-sky (clear-sky) conditions. Long-term simulations show that aerosol DFE increases 2.9% yr(-1) under all-sky conditions mainly because of a downward trend in cloud amount. This study suggests that the impacts of aerosols and cloud should be considered in projecting future changes of ecosystem productivity under varied emission scenarios.
