In this paper, focusing on one major source of BrC, water-soluble(WSOC) and water-insoluble organic carbon (WISOC) from residential solid fuel combustions were characterized by FT-ICR MS, and evaluated for their quantitative relationship with mass absorption efficiency (MAE).
I think the paper is well and clearly written and the experimental and analytical components sound. More minor comments with some requests for clarification on the annotated pdf attached.

Short summary

Brown carbon (BrC) is related to radiative forcing and climate change. The BrC fraction from residential coal and biomass burning emissions, which were the major source of BrC, was characterized at the molecular level. The CHOS aromatic compounds explained higher light absorption efficiencies of biomass burning emissions compared to coal. The unique formulas of coal combustion aerosols were characterized by higher unsaturated compounds, and such information could be used for source appointment.
