Fig. 3: The contributions of light-absorbing components within individual BC particles.
From: Absorption enhancement and shielding effect of brown organic coating on black carbon aerosols

For SOAclean scenario (A) including BC core and lensing effect; For SOABrC scenario (B) including BC core, BrC, lensing effect, and shielding effect. Individual particles with increasing SOAclean (A) and SOABrC (B) thickness clockwise. Each segment represents wavelengths from 350–700 nm. “▲” in B indicates the present of shielding effect (black column below 0).
