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.
