| Research Abstract |
In this study, behaviors and direct radiative effects of carbonaceous aerosols (black carbon, BC, and organic aerosol, OA) have been studied by making observations and box/3D model calculations. The models developed in this study successfully reproduced observed features of BC mixing state and vertical profile of transport efficiency. Model calculated radiative effects of aerosols, such as aerosol optical depth and single scattering albedo were also consistent with observations resulting in improvement in estimations of direct radiative effects.
