Abstract. Atmospheric aerosol particles may undergo liquid-liquid phase separation (LLPS) when exposed to varying relative humidity. In this study, we model how the change in morphology affects the short wave radiative forcing, in particular for particles containing organic carbon as a molecular absorber, often termed brown carbon (BrC). Preferentially, such an absorber will redistribute to the organic phase after LLPS. We limited our investigation to particle diameters between 0.04–0.5 μm, atmospherically relevant organic-to-inorganic mass ratios typical for aged aerosol (1:4 < OIR < 4:1), and absorptivities ranging from zero (purely scattering) to highly absorbing brown carbon. For atmospherically relevant O:C ratios, core-shell morphology is expected for phase-separated particles. We compute the scattering and absorption cross-sections for realistic eccentric core-shell morphologies. For the size range of interest here, we show that assuming the core-shell morphology to be concentric is sufficiently accurate and numerically much more efficient than averaging over eccentric morphologies. In the UV-region, where BrC absorbs strongest, phase-separated particles may exhibit a scattering cross-section up to 50 % larger than those of homogenously mixed particles, while their absorption cross-section is up to 20 % smaller. Integrating over the full solar spectrum, due to the strong wavelength dependence of BrC absorptivity, limits the short wave radiative impact of LLPS. For particles with very substantial BrC absorption there will be a radiative forcing enhancement of 4 %–11.8 % depending on the Ångström exponent of BrC absorptivity. However, for those of moderate absorptivity, LLPS will have no significant short-wave radiative impact.
