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…

Characterization of Aerosol Organics by LC-MSn

Lead Institution
Desert Research Institute
Principal Investigator
Barbara Zielinska
Project type
Large-Scale EMSL Research
In summer, 2009, a comprehensive field study is planned to characterize the effect of organics on the water activity of atmospheric particles under sub- and supersaturated conditions at the Desert…

Characterization of Aerosol Organics by LC-MSn

Lead Institution
Desert Research Institute
Principal Investigator
Douglas Lowenthal
Project type
Exploratory Research
Aerosols contribute to the Earth's radiation balance directly by absorbing and scattering light and indirectly by nucleating cloud droplets which increase planetary albedo. Both effects depend…

Laboratory and Field Studies of Cloud Formation

Lead Institution
Purdue University
Principal Investigator
Daniel Cziczo
Project type
Large-Scale EMSL Research
The relationship between aerosol particles and the formation of clouds is among the most uncertain aspects in our current understanding of climate change. Warm clouds have been the most extensively…
