标题： A Dataset of Weather Station-Scale Photosynthetic Phenology in Mid- to High-Latitude Regions of the Northern Hemisphere

摘要： 本研究从2001年至2019年北半球中高纬度地区的气象站尺度每日GPP数据中提取了光合物候指标（SOS, POS, EOS）。 所得数据集覆盖近60,000个站点年，超过1,000个站点保持完整的19年记录。 结果揭示了显著的空间变异，不同植被类型和干旱区呈现出不同的趋势。 与通量网络和基于卫星的产品相比，该数据集大大提高了物候研究的数据可用性，并为评估局部水热条件和极端气候事件对物候的影响提供了坚实的基础。 显示英文摘要

摘要： This study extracted photosynthetic phenology indicators (SOS, POS, EOS) from daily GPP data at the weather-station scale for the mid- to high-latitude regions of the Northern Hemisphere from 2001 to 2019. The resulting dataset covers nearly 60,000 site-years, with more than 1,000 stations maintaining complete 19-year records. Results reveal pronounced spatial variability, with distinct trends across vegetation types and aridity zones. Compared with flux networks and satellite-based products, this dataset greatly enhances data availability for phenology studies and provides a solid foundation for assessing the impacts of local hydrothermal conditions and extreme climate events on phenology.
