Integrating SWOT with Multi-Source Satellite Observations for Spatio-temporal Characterization of Water Level, Storage Dynamics, and Drought Conditions in Zhelin Reservoir

This dataset provides the processed data supporting the analyses presented in the manuscript "Integrating SWOT with Multi-Source Satellite Observations for Spatio-temporal Characterization of Water Level, Storage Dynamics, and Drought Conditions in Zhelin Reservoir." It contains monthly time series of reconstructed water level, water surface area, reservoir storage, Remote Sensing Drought Index (RS-DSI), and ERA5-derived hydroclimatic variables, including precipitation, runoff, evapotranspiration, and air temperature, for the period January 2014–December 2025. The original satellite observations (SWOT, Sentinel-1, Sentinel-2, and Landsat) and ERA5 products are publicly available from their respective providers; therefore, only the processed datasets generated in this study are included in this repository.
