The TOC/DBC ratio determines whether BC particles can be redistributed into organic coatings from inorganic salt cores. When the organic coating is non-absorbing, the light absorption of internally mixed particles containing one and two BC reduces by 28-34% following the BC redistribution. Further, the radiative absorption of BC in the background air is overestimated by ~18% in most models that assume internally mixed BC aerosols to be the core-shell model.
