Monitoreo de la variación del almacenamiento de agua en la cuenca del Medio y Bajo Paraná a partir de datos GRACE, GRACE FO, TRMM y GLDAS

<p>GRACE (Gravity Recovery and Climate Experiment) is a satellite mission that can monitor mass distributions in the Earth system, which closely related to consequences of climate change. This gravimetric allows obtain monthly variations Earth’s gravity field, be associated with water variations, after removing effects oceanic tides solid Earth, as well non-tidal atmospheric contributions. In this work, data from GRACE (2002-2017) FO (since 2018) were used analyze variation Middle Low Paraná river basin. The interpretation results was carried out by associating anomalies derived information TRMM global rainfall mission. Monthly maps precipitation produced, made possible thorough analysis at regional level redistribution basin, its connection El Niño La Niña events took place period under study. deficits shown 2009 are, fact, intense episode occurred 2008-2009; while excess storage depicted on 2016 2019 connected phenomenon. Moreover, has also detected drought different sectors between 2011-2012, together floods years 2007 2010. GRACE-derived changes compared independent components balance region using hydrological models estimates. Finally, temporal groundwater soil part (surface water, moisture) analyzed Global Land Data Assimilation System GLDAS. variables showed good correlation them, reaching values <span> ~</span>r = 0.80.</p>
