There is a fundamental lack of understanding in processes involving aerosols and clouds that include important mechanisms such as precipitation, climate change, cloud formation, and more. Airborne sea spray aerosol (SSA) particles show diversity in their compositions that is highly dependent on the complex biological, chemical, and physical processes of the subsurface and sea surface microlayer. The hygroscopicity of inorganic salts and chemically complex set of biologically-derived components of SSA and the mixtures of these compounds with sodium chloride is investigated using Hygroscopicity Tandem Differential Mobility Analyzer (HTDMA) under sub-saturated conditions.Results on the chemical changes of nascent SSA via marine aerosol reference tanks in polluted conditions is also reported using single particle micro-Raman Spectroscopy for particles collected during the 2016 summer experiment at the Center for Aerosol Impacts on Climate and the Environment.
