Panet M. Diament Institut de Physique du Globe de Paris (associated with the CNRS and the University Paris 7), Paris, France LAREG, Institut Géographique National, Marne-La-Vallée, France For more than four years, the GRACE pair of satellites have been orbiting the Earth, monitoring the time variable mass distribution for scales ranging from regional to global. The GRACE data have been released for a broad scientific community and sets of gravity fields are available. This paper shows that there are evidences at interrannual time scales for the presence of ENSO signal in the data, strongly correlated with the hydrological mass distribution, and also similar to the expected hydrological signature associated with the ENSO cycle. This signal dominates, at global scale, the one associated with geodynamic sources. Andersen O. B. and Hinderer, J.: Global inter-annual changes from GRACE: Early results , Geophys. Res.
