  abstract = {{T}he amount of water stored and moving through the surface water bodies of large river basins (river, floodplains, wetlands) plays a major role in the global water and biochemical cycles and is a critical parameter for water resources management. {H}owever, the spatiotemporal variations of these freshwater reservoirs are still widely unknown at the global scale. {H}ere, we propose a hypsographic curve approach to estimate surface freshwater storage variations over the {A}mazon basin combining surface water extent from a multi-satellite-technique with topographic data from the {G}lobal {D}igital {E}levation {M}odel ({GDEM}) from {A}dvance {S}paceborne {T}hermal {E}mission and {R}eflection {R}adiometer ({ASTER}). {M}onthly surface water storage variations for 1993-2007 are presented, showing a strong seasonal and interannual variability, and are evaluated against in situ river discharge and precipitation. {T}he basin-scale mean annual amplitude of similar to 1200 km(3) is in the range of previous estimates and contributes to about half of the {G}ravity {R}ecovery {A}nd {C}limate {E}xperiment ({GRACE}) total water storage variations. {F}or the first time, we map the surface water volume anomaly during the extreme droughts of 1997 ({O}ctober-{N}ovember) and 2005 ({S}eptember-{O}ctober) and found that during these dry events the water stored in the river and floodplains of the {A}mazon basin was, respectively, similar to 230 (similar to 40%) and 210 (similar to 50%) km(3) below the 1993-2007 average. {T}his new 15 year data set of surface water volume represents an unprecedented source of information for future hydrological or climate modeling of the {A}mazon. {I}t is also a first step toward the development of such database at the global scale.},
