Abstract :
In this study, by processing the 78 months of GRACE Satellite data, validates the performance of GRACE solutions in the detection of water mass variations and compared with tidal data derived water circulation cycle of the Great Lakes. The results show that the GRACE monthly gravity field model can reflect the changes in the Great Lakes area, including the annual and seasonal changes. Combination of satellite altimetry data to further understand the water cycle of Caspian Sea, that is between groundwater and lake water infiltration cycle.
