The effects of atmospherically relevant heterogenous aging on ambient nascent sea spray aerosols (nSSA) physicochemical properties, such as morphology, composition, phase state, water uptake and their size-dependent particle-to-particle variability remained poorly understood. Thus, current study investigates these physicochemical properties, by focusing on heterogeneously aged SSA (hetSSA, size range of 0.1−0.6 μm) generated during a mesocosm study. The hetSSA were generated by exposing nSSA to OH radicals with 4-5 days of atmospheric time-equivalent aging. Filter-based thermal optical analysis, atomic force microscopy (AFM), and AFM photothermal infrared spectroscopy (AFM-PTIR) were utilized. Results collected on hetSSA physicochemical properties were compared with nSSA, collected during the same study. Filter-based measurements
