Poyang Lake Surface Area and Water Storage Time Series Derived Using SWOT-FLASH

This dataset provides a time series of water surface area and water storage of Poyang Lake from July 2023 to July 2025, with a total of 30 observation records. The data covers the main lake of Poyang Lake and the surrounding sub lakes that are not connected in hydrology within the research scope. The total water reserves of the lake are estimated using the SWOT-FLASH method, which can be used to analyze the seasonal changes in the water surface area and water reserves of Poyang Lake and provide data support for hydrological regulation and storage research of the lake.
