Multi-source Satellite Altimetry Water Level Dataset for 11 Representative Lakes on the Tibetan Plateau (2010–2026)

This dataset provides high-precision, long-term water-level time series for 11 representative lakes on the Tibetan Plateau (TP) from 2010 to 2026. To overcome the spatiotemporal limitations of single-mission satellite altimetry, it integrates CryoSat-2 and Sentinel-3 observations using a multilevel robust anomaly-detection framework to accurately capture the dynamic variations of regional lake levels. The data is stored in CSV format, with each file consisting of three columns: date (the observation or reconstruction date), H_final (the calculated water level in meters, m), and source (the specific satellite mission or data origin).
