. Large uncertainties remain when estimating the warming effects of ambientblack carbon (BC) aerosols on climate. One of the key challenges in modelingthe radiative effects is predicting the BC light absorption enhancement,which is mainly determined by the mass ratio (MR) of non-BC coating material toBC in the population of BC-containing aerosols. For the same MR, recentresearch has found that the radiative absorption enhancements by BC are alsocontrolled by its particle-to-particle heterogeneity. In this study, the BCmixing state index (χ) is developed to quantify thedispersion of ambient black carbon aerosol mixing states based on binarysystems of BC and other non-black carbon components. We demonstrate that theBC light absorption enhancement increases with χ for the sameMR, which indicates that χ can be employed as a factor toconstrain the light absorption enhancement of ambient BC. Our framework canbe further used in the model to study the radiative effects of black carbon onclimate change.
