Alpine lakes in the interior of Tibet, the endorheic Changtang Plateau (CP), serve as "sentinels" of regional climate change. Recent studies indicated that accelerated climate change has driven a widespread area expansion in lakes across the CP, but comprehensive and accurate quantifications of their storage changes are hitherto rare. This study integrated optical imagery and digital elevation models to uncover the fine spatial details of lake water storage (LWS) changes across the CP at an annual timescale after the new millennium (from 2002 to 2015). Validated by hypsometric information based on long-term altimetry measurements, our estimated LWS variations outperform some existing studies with reduced estimation biases and improved spatiotemporal coverages. The net LWS increased at an average rate of 7.34 (±0.62) Gt yr-1 (cumulatively 95.42 (±8.06) Gt), manifested as a dramatic monotonic increase of 9.05 (±0.65) Gt yr-1 before 2012, a deceleration and pause in 2013-2014, and then an intriguing decline after 2014.
