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

<p>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.</p>
