Underlying data: Spatial distribution in surface aerosol light absorption across India

The dataset contains the measured PM2.5 concentrations (µg/m^3), spectral absorption coefficients (Mm^-1), mass absorption cross-section (m^2/g), absorption Angstrom exponents, and the estimated fraction of absorption by brown carbon particles.本数据集涵盖实测PM2.5浓度（单位：µg/m³）、光谱吸收系数（spectral absorption coefficients，单位：Mm⁻¹）、质量吸收截面（mass absorption cross-section，单位：m²/g）、吸收埃指数（absorption Angstrom exponents），以及棕碳颗粒（brown carbon particles）的吸收占比估算结果。
