Recent Research Highlights
Insight of Physical Biases Using Simpler GCM
Marine boundary-layer clouds remain poorly predicted in global climate models due to multiple entangled uncertainty sources. Our recent ACP paper uses the in situ observations from a recent field campaign to constrain and evaluate cloud physics in a simplified version of climate model. Progress and remaining issues in the cloud physics parameterizations are identified. We systematically evaluate the impacts of large-scale forcing, microphysical scheme, and aerosol concentrations on the cloud property.
Direct Observational Constraints on Black Carbon Forcing
Black carbon (BC) is the largest warming agent amoung all aerosol species. Our recent paper on One Earth based on our particle level observations reveal multi-level microphysical complexities in BC-containing particles, and these explain the lower observed BC absorption. Our another recent paper on JAMES develops an improved aerosol optical model in a global climate model to better account for those observations.
