Congratulations, Dr. Yunzhu Zhao!

Dr. Yunzhu Zhao 2014 Ph.D. Environmental Engineering Molecular Characterization of Atmospheric Organic Matter in Biogenic Secondary Organic Aerosol, Ambient aerosol and Clouds Dissertation Abstract: Atmospheric aerosol affects the Earth’s energy budget, reduces visibility and influences human health. The organic composition of aerosol is quite complex and continuously evolves through various atmospheric processes. To gain a deeper understanding of the molecular composition

Research Project to Study Ambient Aerosol Composition

Collaborative Research: Hygroscopic Properties of Aerosol Organics NSF Atmospheric Chemistry Program, 2009-2012 Aerosols affect the Earth’s radiation balance directly by scattering sunlight and indirectly through their role as cloud condensation nuclei (CCN). An increase in the number of CCN leads to more numerous but smaller cloud droplets and increased cloud albedo. Current estimates of direct and indirect effects, -0.9 to
