Characterization of Brown Carbon absorption in different European environments through source contribution analysis

This dataset provides modeled OA mass concentrations and absorption coefficients across 12 European stations, generated using the Multiscale Online Nonhydrostatic Atmosphere Chemistry (MONARCH) model. The data is provided in NetCDF format and includes the following: Mass Concentrations: For each station, the dataset includes OA mass concentrations categorized by emission sources: Residential (poaresi) Traffic (poatraf) Shipping (poaship) Fires (poagfas) Other sources (poaothr) Secondary organic aerosols (SOA) Absorption Coefficients: The absorption coefficient of BrC at 370 nm (AbsBrC370) is calculated for each station. The dataset includes two approaches: Aggregated data across all stations Data separated by individual stationsAdditionally, results are provided for specific cases (Case 4 and Case 5).本数据集提供了覆盖欧洲12个观测站的建模有机气溶胶（Organic Aerosol, OA）质量浓度与吸收系数，采用多尺度在线非静力大气化学（Multiscale Online Nonhydrostatic Atmosphere Chemistry, MONARCH）模型生成。 数据集以NetCDF格式提供，包含以下内容： 一、质量浓度：针对每个观测站，数据集包含按排放源分类的有机气溶胶质量浓度： - 生活源（poaresi） - 交通源（poatraf） - 航运源（poaship） - 野火源（poagfas） - 其他源（poaothr） - 二次有机气溶胶（Secondary Organic Aerosols, SOA） 二、吸收系数：针对每个观测站，计算得到370 nm波长下棕碳（Brown Carbon, BrC）的吸收系数（AbsBrC370）。数据集包含两类数据形式： - 所有观测站的聚合数据 - 分单个观测站的分离数据 此外，数据集还提供了特定案例（案例4与案例5）的计算结果。
