Abstract: Gravity Recovery and Climate Experiment (GRACE) mission is dedicated to measuring temporal variations of the Earth's gravity field. In this study, the Stokes coefficients made available by Groupe de Recherche en Géodésie Spatiale (GRGS) at a 10-day interval were converted into equivalent water height (EWH) for a ~4-year period in the Amazon basin (from July-2002 to May-2006). The seasonal amplitudes of EWH signal are the largest on the surface of Earth and reach ~ 1250mm at that basin's center. Error budget re… Show more

“…Our results indicate that GRACE data may represent the TWS change in the Brazilian Cerrado satisfactorily; allowing assessment of the seasonality of the water balance in this region. These results are consistent with those reported by Almeida et al (2012) and Frappart et al (2013) for the Amazon region. The El Niño events of 2007 and 2010 are probably responsible for the major droughts in the watersheds studied.…”
