<b>EddyChina2023-GPP</b>

The EddyChina2023 dataset integrates eddy covariance measurements from diverse ecosystems across China's climatic zones. This compilation includes: 11 sites established by the authors, 7 sites from ChinaFLUX, and 132 sites extracted from peer-reviewed literature. Selection criteria required: eddy covariance measurements (excluding static chambers) with a minimum of one year of continuous observations, and detailed documentation of instrumentation, data collection, and processing methods. All site data underwent rigorous quality control and gap-filling procedures . While the dataset spans China's climatic gradient, coverage remains sparser in the cold-dry northwest and hot-wet regions.EddyChina2023数据集整合了中国不同气候区各类生态系统的涡度协方差（eddy covariance）观测数据。本数据集包含三类观测站点：作者自建的11个站点、中国通量观测研究网络（ChinaFLUX）提供的7个站点，以及从同行评议文献中提取的132个站点。其筛选标准为：需采用涡度协方差观测方法（排除静态箱法）、具备至少连续一年的观测序列，且包含仪器设备、数据采集与处理方法的详细文档记录。所有站点数据均经过严格的质量控制与间隙填补流程。尽管该数据集覆盖了中国的气候梯度，但在寒冷干旱的西北地区与湿热地区的站点覆盖仍较为稀疏。
