title: Data for Manuscript entitled "Satellite evidence of unequal basin-scale recovery from severe droughts"

description: This dataset supports the study on the assessment of whether—and how—global river basins recover from recent severe droughts through an observation-based analytical framework. It contains data and code used for analysis and visualization in Figures 1 to 4 of the associated manuscript.
