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…
