Short summary
The understanding of the absorption Ångstrom exponent (AAE) of aged black carbon (BC) particles affected by their microphysics is numerically evaluated. With key sensitive microphysical parameters, a simple parameterization of the AAE of coated BC with a size distribution is proposed. It is found that BC coated by thin brown carbon with more large particles shows an AAE smaller than pure BC particles. Our findings improve the understanding and application of the AAE of BC with brown coatings.
