In this study, a multi-satellite approach is proposed to estimate the water stored in the floodplains of the Orinoco Basin at a monthly time-scale using remotely-sensed observations of surface water from the Global Inundation Extent Multi-Satellite (GIEMS) and stages from Envisat radar altimetry. Surface water storage variations over 2003\u20132007 exhibit large interannual variability and a strong seasonal signal, peaking during summer, and associated with the flood pulse. The volume of surface water storage in the Orinoco Basin was highly correlated with the river discharge at Ciudad Bolivar (R = 0.95), the closest station to the mouth where discharge was estimated, although discharge lagged one month behind storage. The correlation remained high (R = 0.73) after removing seasonal effects. Mean annual variations in surface water volume represented ~170 km3, contributing to ~45% of the Gravity Recovery and Climate Experiment (GRACE)-derived total water storage variations and representing ~13% of the total volume of water that flowed out of the Orinoco Basin to the Atlantic Ocean.<\/jats:p>","DOI":"10.3390\/rs70100089","type":"journal-article","created":{"date-parts":[[2014,12,26]],"date-time":"2014-12-26T05:52:39Z","timestamp":1419573159000},"page":"89-110","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Surface Freshwater Storage Variations in the Orinoco Floodplains Using Multi-Satellite Observations"],"prefix":"10.3390","volume":"7","author":[{"given":"Fr\u00e9d\u00e9ric","family":"Frappart","sequence":"first","affiliation":[{"name":"GET-GRGS, UMR 5563, CNRS\/IRD\/UPS, Observatoire Midi-Pyr\u00e9n\u00e9es, 14 Avenue Edouard Belin, 31400 Toulouse, France"},{"name":"LEGOS-GRGS, UMR 5566, CNES\/CNRS\/IRD\/UPS, Observatoire Midi-Pyr\u00e9n\u00e9es, 14 Avenue Edouard Belin, 31400 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6305-6253","authenticated-orcid":false,"given":"Fabrice","family":"Papa","sequence":"additional","affiliation":[{"name":"LEGOS-GRGS, UMR 5566, CNES\/CNRS\/IRD\/UPS, Observatoire Midi-Pyr\u00e9n\u00e9es, 14 Avenue Edouard Belin, 31400 Toulouse, France"},{"name":"Indo-French Cell for Water Sciences, IRD-IISc Joint International Laboratory, Indian Institute of Science, Bangalore 560012, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoann","family":"Malbeteau","sequence":"additional","affiliation":[{"name":"CESBIO, UMR 5126, CNES\/CNRS\/IRD\/UPS, Observatoire Midi-Pyr\u00e9n\u00e9es, 14 Avenue Edouard Belin, 31400 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Le\u00f3n","sequence":"additional","affiliation":[{"name":"Facultad de Ingenier\u00eda y Administraci\u00f3n, Universidad Nacional de Colombia, sede Palmira 76520000, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guillaume","family":"Ramillien","sequence":"additional","affiliation":[{"name":"GET-GRGS, UMR 5563, CNRS\/IRD\/UPS, Observatoire Midi-Pyr\u00e9n\u00e9es, 14 Avenue Edouard Belin, 31400 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine","family":"Prigent","sequence":"additional","affiliation":[{"name":"LERMA, CNRS, Observatoire de Paris, 75000 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luc\u00eda","family":"Seoane","sequence":"additional","affiliation":[{"name":"GET-GRGS, UMR 5563, CNRS\/IRD\/UPS, Observatoire Midi-Pyr\u00e9n\u00e9es, 14 Avenue Edouard Belin, 31400 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3609-7524","authenticated-orcid":false,"given":"Fr\u00e9d\u00e9rique","family":"Seyler","sequence":"additional","affiliation":[{"name":"ESPACE-DEV, UMR 228, IRD\/UAG\/UM2\/UR, 34961 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"St\u00e9phane","family":"Calmant","sequence":"additional","affiliation":[{"name":"LEGOS-GRGS, UMR 5566, CNES\/CNRS\/IRD\/UPS, Observatoire Midi-Pyr\u00e9n\u00e9es, 14 Avenue Edouard Belin, 31400 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2014,12,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"373","DOI":"10.1038\/359373a0","article-title":"The hydrological cycle and its influence on climate","volume":"359","author":"Chahine","year":"1992","journal-title":"Nature"},{"key":"ref_2","unstructured":"Parry, M.L., Canziani, O.F., Palutikof, J.P., van der Linden, P.J., and Hanson, C.E.
