Description
TITLE: Radiative Effect and Climate Impacts of Atmospheric Dust
ABSTRACT: Atmospheric dust plays a key role in the Earth’s system by interacting with radiation, clouds, atmospheric chemistry, and biogeochemistry, thereby affecting air quality, climate, hydrological and biogeochemical cycles. However, current Earth system models are still associated with large dust biases, and dust radiative effect and impacts on climate are highly uncertain. In this talk, I will first introduce the Modal Aerosol Module (MAM) in the DOE’s Energy Exascale Earth System Model (E3SM) and National Center for Atmospheric Research’s Community Earth System Model (CESM) which I have been playing a key role in developing since 2006. I will then provide an overview of recent dust related work conducted in my group, which includes: (1) understanding processes that control dust spatial distributions; dust size distribution (coarse mode) and minerology effects; (2) exploring sources and radiative effects of anthropogenic dust; and (3) studying the effects of dust on mixed-phase clouds by acting as ice nucleating particles (INPs).
