Source-Resolved Dataset of Aromatic Condensation and EC-Normalized Light Absorption of Freshly Emitted Black Carbon from Major Combustion Sources

This dataset contains source-resolved measurements of freshly emitted carbonaceous aerosols from residential coal combustion, biomass burning, on-road diesel vehicles, and non-road diesel engines. Variables include sample information, modified combustion efficiency, MACEC at 632 nm, BPCA concentrations and composition, B6CA/B5CA ratios, NCOOH, estimated aromatic domain size, source-specific regression results, and fixed-effects ANCOVA outputs. The dataset supports analyses of the association between aromatic condensation and EC-normalized light absorption across major combustion sources.
