Investigating the ice nucleation activity of organic aerosol
(Massachusetts Institute of Technology, 2020)
Emissions of aerosol particles and their precursors affect climate directly by scattering radiation and indirectly by altering cloud properties. Aerosol-induced ice nucleation includes several processes that impact cloud ...
Impacts of emission policies in China on air pollution and human health
(Massachusetts Institute of Technology, 2019)
Precursor emissions of air pollution can be reduced at emitting sources by end-of-pipe control policies or as co-benefits of climate policies that limit fossil fuel. Identifying cost-effective control strategies requires ...
Understanding the chemistry of atmospheric particles using single particle mass spectrometry
(Massachusetts Institute of Technology, 2017)
This thesis explores ways in which single particle mass spectrometry can be extended, whether through hardware improvements, or through the use of advanced data processing techniques to provide new kinds of aerosol chemistry ...
Quantifying mercury surface fluxes by combining atmospheric observations and models
(Massachusetts Institute of Technology, 2016)
Mercury (Hg) is a critical environmental concern. Although an important component of its biogeochemical cycle, large uncertainties still exist in the estimates of surface fluxes of mercury. Three projects presented in this ...
