英文摘要	The composition, morphology, and mixing structure of individual cloud residues (RES) and interstitial particles (INT) at a mountain-top site were investigated. Eight types of particles were identified, including sulfate-rich (S-rich), S-organic matter (OM), aged soot, aged mineral, aged fly ash, aged metal, fresh mixture, and aged mixture. A shift of dominant particle types from S-rich (29 %) and aged soot (27 %) in the INT to S-OM (24 %) and aged mixture (22 %) in the RES is observed. In particular, particles with organic shells are enriched in the RES (30 %) relative to the INT (12 %). Our results highlight the in-cloud formation of more oxidized organic shells on the activated particles. We also show that in-cloud processes may result in less compact soot, with the fractal dimensions (Df) of soot in the RES (1.82 ± 0.12) lower than those in the INT (2.11 ± 0.09). This research emphasizes the role of in-cloud processes on the chemistry and microphysical properties of individual particles. Given that organic coatings may determine the particle hygroscopicity, activation ability, and heterogeneous chemical reactivity, the increase of OM-shelled particles upon in-cloud processes should have considerable implications.
