Hailong Wang has wide-ranging research expertise in atmospheric aerosols, cloud physics and dynamics, aerosol-cloud-precipitation-climate interactions, light-absorbing impurities in snowpack and sea ice, radiative feedbacks, and high-latitude climate change and its associated impacts. His research has generated important scientific discoveries and advanced our fundamental understanding of the role of aerosols in various critical components of Earth’s climate system. This includes the diurnal evolution of shallow cumulus, mesoscale organizations of marine stratocumulus, marine boundary-layer ship-track formation and cloud brightening, cryosphere surface albedo, monsoon precipitation, and regional circulations. Dr. Wang’s recent research also made breakthroughs in the cause and impact of Arctic warming, sea ice and snow loss, and other Arctic environmental changes.

Dr. Wang has also advanced model capabilities for representing aerosols and aerosol-cloud-precipitation interactions in process-oriented atmospheric models and Earth system models. He led the implementation and evaluation of a monotonic advection scheme and a bin-emulating double-moment cloud microphysics scheme in the Weather Research and Forecasting (WRF) model, key to characterizing aerosol-cloud-precipitation interactions at fine scales. The new capabilities in WRF enabled the discovery of the self-organizing nature of marine open-cell and closed-cell cloud structures, as well as benefitting research throughout WRF user community. Dr. Wang led the development of a unique Explicit Aerosol Source Tagging (EAST) technique in two major Earth system models, the Community Earth System Model (CESM) and Energy Exascale Earth System Model (E3SM), opening new areas for aerosol-cloud-climate research within PNNL and the modeling community. EAST has been used for aerosol source attribution, quantification of emission and transport uncertainties, and the characterization of aerosol species (e.g., brown carbon) with source-dependent attributes, which also provide a scientific basis to guide air pollution and climate mitigation strategies. Dr. Wang leads efforts to develop aerosol representations in E3SM that incorporate the improved scientific understanding of aerosol effects, remove model deficiencies, and reduce uncertainties in aerosol radiative forcing. The improved versions of CESM and E3SM have been widely used to better understand aerosols in the Earth system and quantify their effects on clouds, radiation, air quality, and climate.
