Impact of in-cloud aqueous processes on the chemical compositions and morphology of individual atmospheric aerosols
<p>The composition, morphology, and mixing structure of individual cloud residues (RES) and interstitial particles (INT) at a mountaintop site were investigated. Eight types of particles were identified, including sulfate-rich (S-rich), S-organic matter (OM), aged soot, aged mineral dust, aged...

| description | <p>The composition, morphology, and mixing structure of
individual cloud residues (RES) and interstitial particles (INT) at a
mountaintop site were investigated. Eight types of particles were
identified, including sulfate-rich (S-rich), S-organic matter (OM), aged
soot, aged mineral dust, aged fly ash, aged metal, refractory, and aged
refractory mixture. A shift of dominant particle types from S-rich (29 %)
and aged soot (27 %) in the INT to aged refractory
mixture (23 %) and S-OM (22 %) in the RES is observed. In particular, particles with
organic shells are enriched in the RES (27 %) relative to the INT
(12 %). Our results highlight that the formation of more oxidized organic
matter in the cloud contributes to the existence of organic shells after
cloud processing. The fractal dimension (<span class="inline-formula"><i>D</i><sub>f</sub></span>), a morphologic parameter to
represent the branching degree of particles, for soot particles in the RES
(1.82 <span class="inline-formula">±</span> 0.12) is lower than that in the INT (2.11 <span class="inline-formula">±</span> 0.09), which
indicates that in-cloud processes may result in less compact soot. This
research emphasizes the role of in-cloud processes in 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.</p> |
