Short summary

Black carbon, primary brown carbon and secondary brown carbon are the leading light-absorbing carbonaceous aerosols (LACs) that contribute significantly to climate change. We modified the GEOS-Chem model to simulate the climate change by LACs based on a local emission inventory and explored the impacts of LAC properties and atmospheric variables on the corresponding direct radiative forcings (DRFs) in seven regions of China. The study confirms the warming effect of LACs and deepens our knowledge of their climatic effects.
