Short summary
The absorption enhancement of black carbon with brown coatings is investigated. In addition, the ratio of the absorption of BC coated by brown carbon (BrC) to an external mixture of BrC and BC (Eabs_internal) is also investigated. The lensing effect and sunglasses effect are clearly defined. The applicability of the core–shell sphere model was investigated. The effects of the size distribution, fractal dimension, and wavelength dependency are also explored.
