Short summary
We develop a novel method in this work for in situ measurements of the morphology and effective density of ambient In-BC cores using a volatility tandem differential mobility analyzer and a single-particle soot photometer. We find that In-BC cores hardly transform the morphology of BC into a void-free sphere. Taking the morphology and density of ambient In-BC cores into account, our work provides a new insight into the enhancement of light absorption for In-BC particles in the atmosphere.
