Data for "Measuring Light Absorption by Freshly Emitted Organic Aerosols: Optical Artifacts in Traditional Solvent Extraction-Based Methods"

The dataset was used to report optical artifacts in traditional solvent extraction based photometry techniques. Biomass fuels from different sources were combusted and the absorption coefficients obtained using solvent-extraction based techniques were compared to their particle-phase counterparts. Trends in the absorption coefficient bias were explored with (1) OC/TC ratios and (2) single scattering albedo (SSA). A linear trend with the OC/TC ratio and SSA was also observed for the biomass burning samples that were investigated. Obtained results and experimental methodology are detailed in the manuscript linked with this dataset.本数据集用于报道基于传统溶剂萃取的光度法中的光学伪影（optical artifacts）。研究人员采集不同来源的生物质燃料并开展燃烧实验，将基于溶剂萃取技术测得的吸收系数与对应颗粒相（particle-phase）吸收系数进行对比。本研究以（1）有机碳/总碳（OC/TC）比值和（2）单散射反照率（single scattering albedo, SSA）为考察指标，探究了吸收系数偏差的变化规律。在所考察的生物质燃烧样品中，同样发现吸收系数偏差与OC/TC比值及单散射反照率存在线性相关关系。本研究的实验方法与所得结果详见与本数据集关联的学术手稿。
