Investigating the distribution and effects of carbonaceous absorbing aerosols over mainland China

BACKGROUND:

Black carbon (BC) and "brown" organic carbon (BrC) particles are emitted to the atmosphere by incomplete combustion. These carbonaceous aerosols efficiently absorb solar radiation, with complicated impacts on climate. Recent studies suggest that BC and BrC may exert a positive feedback on aerosol and atmospheric pollution accumulation. My work involves examining the chemical and meteorological factors that affect atmospheric pollution in China, with a particular focus on carbonaceous absorbing aerosols.

OBJECTIVES

  • Use in situ data to understand the distribution and trends of BC and BrC in China.
  • Improve the ability of models to simulate BC and BrC concentrations over China.
  • Determine the implications for regional climate forcing.
  • Determine the importance of absorbing aerosols in the formation of extreme air pollution events.
