Abstract

Lakes are considered as sentinels of climate change. Water stored in lake is an important component of the land water cycle. Earth Observations offer a unique tool to monitor lakes extent, water levels variations, and hence changes in water volume combing these two variables or one of them with lakes bathymetry. We present here, surface water volume variations combining lake extent from MODIS and water levels from radar altimetry over 01/1995-04/2024 of Lake Titicaca, the second largest lake in South America. Comparisons between water levels from in-situ gauge and from radar altimetry including the recently launched SWOT mission are presented.
