Aerosol light absorption and optical measurements of PTFE membrane filter samples
Description
This dataset was used to reports (1) particle phase optical measurements (absorption optical depth and single scattering albedo measured using multiwavelength integrated photoacoustic spectrometers and (2) filter optical depth measurements for polytetrafluoroethylene (PTFE) membrane filter samples of carbonaceous aerosols generated from combustion of diverse biomass fuels and kerosene (surrogate for fossil fuel combustionDiverse biomass fuels including wood and needles from pine, fir, and sage trees, grass, peat, and cattle dung were burned 30 in a 21 m3 stainless steel combustion chamber located at Washington University (Sumlin et al., 2018, 2017). Flaming, smoldering, and mixed combustion phases were employed (see Sect. S1 in the Supplement) to generate a range of intrinsic aerosol properties: SSA values at 375, 405, and 35 532 nm ranged 0.4–0.99 and absorption Ångström exponents (AÅEs) for 375–532 nm ranged 1.2–6.8. A kerosene lamp was used to generate soot particles
