Dataset for Global estimate of reservoir hydropower storage potential based on SWOT observations

This dataset presents the first global observation-based inventory of reservoir hydraulic head and energy storage potential derived from Surface Water and Ocean Topography (SWOT) observations. By combining satellite-derived water surface elevations with reservoir information, the dataset provides a globally consistent assessment of reservoir energy storage resources and their variability.Unlike previous assessments that primarily relied on dam characteristics or model-based estimates, this dataset is founded on direct satellite observations, enabling a dynamic characterization of hydraulic head and reservoir energy storage potential.The dataset supports investigations of hydropower resources, reservoir energy storage, climate resilience, sustainable energy transitions, and coupled water-energy systems at regional to global scales.
