Short summary
To determine important sources of aerosols during the Southern Oxidant and Aerosol Study (SOAS), as well as their mixing with secondary species, individual particles were analyzed with electron and X-ray microscopy to determine size and chemical composition. Secondary organic aerosol, sea spray aerosol, and mineral dust each dominated during different periods. Particles were less similar chemically to each other than is commonly assumed, which is important for air quality and climate models.
