| Zusammenfassung |
| Several satellite altimetry missions have been launched during the past decades and have demonstrated the accuracy level and the effectiveness of satellite altimetry as a technique to monitor water level variations of inland water bodies. The objective of the present study is to detect the water level fluctuations from a multi- mission approach for a better understanding of the behavior over long periods and obtain a better time resolution when overlaps exist, while trying to improve the accuracy improvement. We choose several major freshwater lakes located in the Yangtze River basin in China: Dongting Lake, Poyang Lake, Chao Lake, Hongze Lake and Taihu Lake. The altimetry data are obtained from the complete missions of Envisat, Topex and Jason-2. The timeseries of each target lake is achieved under the consideration of the error assessment between different missions. |
