My research interest focuses on the sources, the transport and the sinks of carbonaceous aerosols in the atmosphere and the associated climate effect.
Current research at Harvard University
I am currently involved in HIPPO (the HIAPER Pole-to-Pole Observations) project. My work focuses on combining aircraft data and GEOS-Chem model to improve the understanding of factors controlling the global transport of black carbon in the atmosphere. I also participate in the planning stages and provide chemical forecasting for the ongoing HIPPO-IV campaign.
I have also involved in NASA ARCTAS (Arctic Research of the Composition of the Troposphere from Aircraft and Satellites) data analysis. My work is to use aircraft observations of BC and OA, together with long-term records of BC observations at surface sites and in snow to better understand sources of carbonaceous aerosols in the Arctic, the deposition of BC to snow, and implications for regional radiative forcing.
