Description

The scarcity of groundwater storage change data at the global scale hinders our ability tomonitor groundwater resources effectively. In this study, we assimilate a state‐of‐the‐art terrestrialwater storage product derived from Gravity Recovery and Climate Experiment (GRACE) satelliteobservations into NASA's Catchment land surface model (CLSM) at the global scale, with the goal ofgenerating groundwater storage time series that are useful for drought monitoring and other applications.Evaluation...[Show more]
