My primary research goal is to improve the understanding of aerosol climate impact. My research focuses on quantifying the aerosol change in the past and future, determining the underlying causes of such variability, uncovering the mechanism by which aerosol modifies the climate-system. I use global aerosol-climate models with observations of the atmosphere from all scales to answer these questions. During my PhD study at University of Michigan, I developed a global Secondary Organic Aerosol (SOA) model using state-of-the-art process-level understandings of the SOA formation mechanism, and quantified the SOA climate radiative forcing. At PNNL, I use the nudging method to quantify the parametric uncertainty in the Community Atmosphere Model version 5 (CAM5). Additionally, I attempt to quantify the aerosol sub-grid variability (SGV) by analyzing the high-resolution model results, with the purpose of developing an aerosol SGV parameterization scheme than can be used in a climate model. I also study the aerosol-cloud-climate interactions by improving the aerosol and cloud microphysics with a multi-scale modeling framwork (MMF) (also known as superparameterization).
