Abstract Black carbon (BC) strongly absorbs solar radiation and has a warming effect on the earth‐atmosphere system. BC experiences continuous aging, making its optical properties great uncertainty due to complex mixing state. To address this issue, we developed sectional model which is capable of tracking both aerosol size core size. This was applied simulate aging process. The atmospheric observational data from slightly polluted case employed drive model. It shown that BC's characteristics tend reach steady state within 12 hr. Our analysis reveals that, in state, distribution BC‐containing particles demonstrates notable characteristic: particle decreases exponentially as increases. exponential relationship provides simplified yet accurate representation steady‐state validated across diverse conditions.
