| 英文摘要 | Lake ice thickness (LIT) serves as a key indicator of cryospheric and hydrological processes, yet its large-scale quantification on the Tibetan Plateau (TP) has long been hindered by limited observations. This study presents the first satellite altimetry-based mapping of LIT across the TP by leveraging multi-mission radar altimetry datasets (Jason-3, Sentinel-3A/B, Sentinel-6A, and SWOT). A numerical waveform fitting algorithm was employed to retrieve LIT from altimetry waveforms, followed by multi-stage quality control to build LIT time series for 170 lakes between 2016 and 2024. Cross validation shows high consistency and reliability of altimetryretrieved LIT. Overall, the mean annual maximum LIT values range from 0.28 to 0.78 m, generally decreasing with lake area and increasing with elevation. Altimetry-derived LIT was then used to correct LIT estimates from ERA5-Land reanalysis to reconstruct long-term LIT time series. Further analysis indicates an overall thinning rate of -0.8 mm yr-1 during the past 3 decades, and temperature emerges as the dominant driver (57.6%), followed by longwave (24.1%) and shortwave radiation (17.6%). This study provides the first consistent, observation-based quantification of LIT across the TP, offering critical insights into the basic understanding of LIT. The resulting dataset establishes a valuable foundation for future assessments of TP lake responses in a warming climate. |
