New Online Coupled Aerosol Climate Model to Better Understand Aerosol’s Climate Effects

Atmospheric aerosols can exert effects on climate, environment and health. However, due to the lack of comprehensive understanding of the interaction mechanism between the aerosol and cloud, there exists deep uncertainty in the estimation of climatic and environmental effects caused by the anthropogenic aerosol. The online coupled aerosol climate model is an important tool to
