Brown Carbon Optical Properties

Optical properties of Brown Carbon aerosol as functions of wavelength (λ), geographic origin, fuel source depth (FSD), and moisture contents (MC). Data for Alaskan peat: four wavelengths, two FSDs, and five MCs for a total of 40 data points. Data for IN peat: four λs and three MCs for a total of 12 data points. Each data point includes the total number concentration (Ntotal), geometric mean diameter (dpg) and geometric standard deviation (σg) of the size distribution as reported by a scanning mobility particle sizer , as well as both components of the complex refractive index (real part n and imaginary part κ) and the single-scattering albedo (SSA). Refractive indices were retrieved with the Python Mie Scattering package (PyMieScatt).

本数据集聚焦棕碳气溶胶（Brown Carbon aerosol）的光学特性随波长（λ）、地理来源、燃料源深度（FSD）与含水率（MC）的变化规律。针对阿拉斯加泥炭样品，设置了4个波长、2种燃料源深度与5种含水率，总计40组数据点；针对IN泥炭样品，设置了4个波长与3种含水率，总计12组数据点。每组数据点均包含扫描迁移率粒径谱仪（scanning mobility particle sizer）测得的总粒子数浓度（Ntotal）、粒径分布的几何平均直径（dpg）与几何标准偏差（σ_g），同时涵盖复折射率的实部n与虚部κ，以及单散射反照率（SSA）。复折射率通过Python米氏散射工具包（PyMieScatt）反演得到。
