Daily Averaged Accumulation Mode Particle Number Concentrations (N100) from 35 Stations (2003-2019)

This dataset contains the number concentrations of particles with dry diameters larger than 100 nm (N100) calculated from particle number size distribution measurements. The dataset includes varying lengths of daily averaged data from 35 measurement stations worldwide, collected during the period from 2003 to 2019. The dataset was utilized in the study titled “Global fields of daily accumulation-mode particle number concentrations using in situ observations, reanalysis data, and machine learning” to train and validate machine learning models. For more detailed information on the dataset, including the specific measurement periods, data processing methods, and station details, please refer to the publication.本数据集包含基于粒子数粒径分布（particle number size distribution）测量结果计算得到的、干粒径大于100 nm的颗粒物数浓度（记为N100）。该数据集涵盖了2003年至2019年间，全球35个观测站点的不同时长的日平均数据。 本数据集已被应用于题为《基于原位观测、再分析数据与机器学习的日均值积聚模颗粒物数浓度全球场（Global fields of daily accumulation-mode particle number concentrations using in situ observations, reanalysis data, and machine learning）》的研究，用于训练并验证机器学习模型。如需了解该数据集的更多详细信息，包括具体观测时段、数据处理方法及站点详情，请参阅该发表论文。
