英文摘要	Absorption enhancements of polydisperse black carbon (BC) aggregates with brown coatings, decomposed into those due to lensing effect (Elen) and blocking effect (Eblo), are numerically studied based on recent observations with an accurate multiple-sphere T-matrix method. Both Elen and Eblo of BC with brown coating are predominantly determined by coated volume fraction of BC in ultraviolet and visible spectral regions, and the impacts of other microphysical parameters of coated BC are trivial if BC is no more than half encapsulated. If more volume fraction of BC is coated, scattering coating can focus more photons onto BC core with stronger lensing effect whereas absorptive coating blocks more photons originally induced by lensing effect onto BC core. The Elen may not be further enhanced with increased shell/core ratio after reaching a threshold, whereas the Eblo has sizable wavelength dependence and becomes close to the Elen in ultraviolet region. Moreover, the lensing and blocking effects of BC with brown coatings are simply parameterized, and the convenient treatments are expected to find wide applications for BC absorption enhancements due to coating. © 2020.
