TL;DR: In this paper, the life cycle of dust, sea salt, sulfate, black carbon and particulate organic matter as simulated by sixteen global aerosol models has been analyzed and the differences among the results (model diversities) for sources and sinks, burdens, particle sizes, water uptakes, and spatial dispersals have been established.

TL;DR: The core version of the Norwegian Climate Center's Earth System Model, named NorESM1-M, is presented in this paper, where a first-order assessment of the model stability, the mean model state and the internal variability based on the model experiments made available to CMIP5 are presented.

TL;DR: In this paper, the authors report on the AeroCom Phase II direct aerosol effect (DAE) experiment where 16 detailed global aerosol models have been used to simulate the changes in the aerosol distribution over the industrial era.

TL;DR: The AeroCom exercise as mentioned in this paper diagnoses multi-component aerosol modules in global modeling and compares simulated global distributions for mass and mid-visible aerosol optical thickness (aot) among 20 different modules.

TL;DR: In this paper, a harmonized estimate for the aerosol di- rect radiative forcing (RF) under all-sky conditions is derived from the difference of two model simulations with prescribed aerosol emissions, one for present-day and one for pre-industrial conditions.
