Short summary

ChinaAI-FSC provides the first large-scale, artificial intelligence (AI)-ready fractional snow cover dataset for China, covering 2000–2022. It integrates observations from the Moderate Resolution Imaging Spectroradiometer, Landsat, and Sentinel-2 satellites and is carefully processed to enable training and evaluation of AI models and large-scale snow mapping. This dataset improves snow monitoring accuracy and supports reproducible research on climate and hydrological processes.
