%X Land water storage changes over 27 large river basins worldwide are calculated from updated monthly RL04 GRACE geoid solutions computed at GFZ from January 2003 to December 2007. Neighborhood basins show similar seasonal phase. The results indicate that the seasonal amplitude in land water storage is 1572.4 km3 from January 2003 to December 2007. The largest annual water volume change is found in the Amazon basin, followed by the Ob, Nile and Niger. Over the 5-year time span, the inter-annual change is about -75.4±40.3 km3/a, while positive trends shown in the Amazon, Lena and Mckenzie basins, and negative in Congo, Mississippi, Yukon, Ganges and Yarlung Zangbo basins. The inter-annual change in land water storage has been increasing since 2006 from both GRACE and GLDAS.
