Quantifying Spectral Absorption of Carbonaceous Aerosols Using A Novel Tracer-Guided Least-Square Method and the Impacts on Radiative Forcing Estimation

The data file includes (1) concentrations of element carbon, organic carbon, metal elements, fine mineral dust, and non-dust water-soluble ions, as well as their respective mass fractions, (2) the absorption coefficients of total carbonaceous aerosols at 405, 445, 635, 780, 808, and 980 nm, as well as the quantified absorption coefficients of black carbon and brown carbon, (3) solar irradiance based on the ASTM G173-03 reference spectrum. The code file contains Python scripts for generating each graph, including calculations of simple radiative forcing, comparisons of black carbon and brown carbon absorption coefficients under different AAE scenarios.
