Weather Station-Scale Photosynthetic Phenology Dataset in the Middle and High Latitudes of the Northern Hemisphere

This dataset includes the start, peak, and end times of the growing season (SOS, POS and EOS), extracted from GPP time series data estimated at weather stations. It covers a total of 57,829 site-years. The dataset provides valuable information for large-scale phenology analysis, ecosystem model validation, and other studies in the carbon cycle and ecology fields.本数据集提取自动气象站估算的总初级生产力（Gross Primary Productivity, GPP）时间序列数据，包含生长季起始期（Start of Growing Season, SOS）、峰值期（Peak of Growing Season, POS）与结束期（End of Growing Season, EOS）三类物候时间节点信息。数据集总计涵盖57829个站点年样本，可为大规模物候分析、生态系统模型验证，以及碳循环与生态学领域的相关研究提供极具价值的支撑数据。
