Short summary
The morphology and effective density of externally mixed black carbon (extBC) aerosols were studied using a tandem technique coupling a DMA with a SP2. The study extended the mass–mobility relationship to large extBC with a mobility diameter larger than 350 nm, a size range seldom included in previous tandem measurements of BC aggregates. On this basis, quantities such as the mass–mobility scaling exponent were revealed for extBC in urban Beijing.
