“…To improve the seasonal and annual predictability of rainfall, runoff, and ET dynamics across the basin, the available in-situ observations were blended with satellite-derived hydrological data and LSMs outputs [18,24,42,47,48]. Further, several research studies have employed multisource remote sensing observations including precipitation [18,49,50], ET and moisture products [47,51,52], and gridded hydrological records [53][54][55] to understand the water resources potentials in the hydrologic source and sink areas [50], investigate the seasonal variability across the entire NRB [20,56,57], and individual hydrologic units, i.e., Lake Victoria [25,58] and the Blue Nile Basin (BNB) [51,55,59]. Consequently, recent research utilized GRACE-TWS data to study the changes in key water storage components and the hydrological mass variation in the basin [24,58].…”
