Fig. 2: Quantifying the size-dependence characteristics of black carbon (BC) mixing state.
From: Locating the missing absorption enhancement due to multi‒core black carbon aerosols
a Different colours represent the number of BC cores (ncore) in each particle, and the histogram is the number distribution of particles with different BC core size (Dc). Dc is the cumulative equivalent volume diameter of all BC cores in a particle. b Two-dimension distribution of particle-to-core diameter ratio (Dp/Dc) and Dc based on the transmission electron microscopy. The smooth line is used for all coated BC particles (black) and their fitting curve (purple). The Boundarycond line means the max Dp/Dc versus Dc via the condensation processing, and beyond Boundarycond line, changes in Dp/Dc are predominantly influenced by coagulation. The Boundarycond line is well described in Chen et al.38 and Sedlacek et al.25. c The range of ncore in different size bins based on the diameter of the whole particle (Dp).
