Short summary

The understanding of the exactly retrieved optically effective aerosol complex refractive index (ACRI) of aged BC affected by their microphysics is numerically evaluated. A simple new ACRI parameterization for heavily coated BC in coarse mode is then proposed. We suggest that, to produce reliable estimates of BC radiative forcing in aerosol–climate models, the optically effective ACRI, rather than the ACRI given by the VWA, appears to be essential, especially for coarse coated BC particles.
