Observed and deweathered source concentrations of black carbon (BC) in Tianjin, China in 2017-2020

This dataset contains 1) the output of a Dispersion Normalized Positive Matrix Factorization (DN-PMF) modeling of a long-term BC dataset measured in Tianjin, China, and 2) the deweathered source contributions of the six identified BC sources.本数据集包含两部分内容：1）针对中国天津地区长期监测的黑碳（Black Carbon, BC）数据集开展的色散归一化正矩阵因子分解（Dispersion Normalized Positive Matrix Factorization, DN-PMF）建模输出结果；2）6种已识别黑碳排放源经去大气风化校正后的源贡献值。
