Measurement report: New insights into the mixing structures of black carbon on the eastern Tibetan Plateau: soot redistribution and fractal dimension enhancement by liquid‒liquid phase separation

This study for the first time found large amounts of liquid-liquid phase separation (LLPS) particles with BC redistributing in organic coatings instead of sulfate cores in the eastern TP atmosphere. The entire particle size, OM-coating thickness, and BC size are key factors that affect the BC redistribution process. The BC redistribution process and high RH both promoted the morphological compaction of soot particles.
