  abstract = {{V}ariations in surface water extent and storage are poorly characterized from regional to global scales. {I}n this study, a multi-satellite approach is proposed to estimate the water stored in the floodplains of the {O}rinoco {B}asin at a monthly time-scale using remotely-sensed observations of surface water from the {G}lobal {I}nundation {E}xtent {M}ulti-{S}atellite ({GIEMS}) and stages from {E}nvisat radar altimetry. {S}urface water storage variations over 2003-2007 exhibit large interannual variability and a strong seasonal signal, peaking during summer, and associated with the flood pulse. {T}he volume of surface water storage in the {O}rinoco {B}asin was highly correlated with the river discharge at {C}iudad {B}olivar ({R} = 0.95), the closest station to the mouth where discharge was estimated, although discharge lagged one month behind storage. {T}he correlation remained high ({R} = 0.73) after removing seasonal effects. {M}ean annual variations in surface water volume represented similar to 170 km(3), contributing to similar to 45% of the {G}ravity {R}ecovery and {C}limate {E}xperiment ({GRACE})-derived total water storage variations and representing similar to 13% of the total volume of water that flowed out of the {O}rinoco {B}asin to the {A}tlantic {O}cean.},
