Dr. Wang has worked at PNNL since 2009. His research falls within the disciplines of atmospheric aerosols, cloud physics and dynamics, boundary-layer meteorology, and climate change. He works extensively on using large-eddy simulations (LES) and observations to advance the process-level understanding of aerosol-cloud-precipitation-radiation interactions and on improving the representations of cloud-aerosol processes in global models. He has also been highly involved in the development the Weather Research and Forecasting (WRF) model and the Community Earth System Model (CESM) to better study aerosols and their effects on clouds, precipitation, radiation and climate. More recently, Wang led the development of a source-tagging technique in CESM to quantify source-receptor relationships of global carbonaceous aerosols and their sensitivity to emission uncertainties, and has been using this modeling tool along with atmospheric and snow/ice-core measurements to systematically quantify sources and radiative forcing of black carbon over the Arctic and in mid-latitude glaciers and seasonal snow.
