Global dataset of nitrogen pool and flux estimates

Dataset of global nitrogen pools and flux estimates from 1955 to 2025 (through May). Data are seperated by domain (terrestrial, aquatic, atmospheric) with an additional tab for data that were not included in the data synthesis (total inputs that were redundant of existing data or data outside the scope of the project). The primary dataset was used to derive a global nitrogen budget, which shows data included in the nitrogen balance calculation and how "best estimates" were derived.1955年至2025年（截至5月）全球氮库（nitrogen pools）与通量（flux）估算数据集。数据按领域（陆地、水生、大气）进行分类，另设工作表存储未纳入数据综合的内容：包括与现有数据重复的总输入数据，或超出项目研究范围的数据。 本核心数据集用于构建全球氮预算，其中展示了纳入氮平衡计算的数据集，以及“最优估算值”的推导过程。
