The Formation and Structure of Tropical Organic/Water Aerosols

Lead Institution
University of Colorado at Boulder
Principal Investigator
Gayfree Ellison
Project type
Large-Scale EMSL Research
Atmospheric aerosols are widely recognized as key elements in many environmental issues ranging from global climate change and visibility to adverse effects on peoples health. Aerosols affect climate…

Secondary Organic Aerosol Formation from Nitrate Photochemistry

Lead Institution
University of California, Irvine
Principal Investigator
Barbara Finlayson-Pitts
Project type
Large-Scale EMSL Research
Secondary organic aerosols (SOA) in the troposphere are a major component of particulate matter and hence of interest with respect to health effects, visibility and radiative forcing. However, their…

Chemistry and Microphysics of Small Particles

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Alla Zelenyuk-Imre
Project type
Large-Scale EMSL Research
This proposal is a continuation of research under EMSL User Proposal #17498. Atmospheric aerosol particles impact the global climate by scattering solar radiation to space and in their role as cloud…

Hygroscopic Properties of Aerosol Organics

Lead Institution
Desert Research Institute
Principal Investigator
Douglas Lowenthal
Project type
Large-Scale EMSL Research
While organics constitute a large fraction of ambient aerosol mass, their role and effect on particle hygroscopic growth and cloud nucleation remains unclear. Organics are most often present in…

Integrated Experimental and Modeling Studies on Aerosol Evolution and Aging

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Rahul Zaveri
Project type
Large-Scale EMSL Research
The objectives of this project are to characterize the time evolution of aerosol size, density, composition, and mixing state in an aerosol chamber, and b) link experiments to the development and…
