Southeast Atmosphere Study (SAS)

Objectives

• Quantify the aerosol composition and physical properties (i.e., volatility, hygroscopicity, and water solubility) using a novel PILS-TD-AMS/CCN system.

• Investigate the effects of anthropogenic emissions on the formation of biogenic secondary organic aerosol.
