GDO Total Water Storage Anomaly (TWSA) (GRACE) (version 2.1.0)
Description
The Total Water Storage (TWS) Anomaly indicator that is implemented in the Copernicus Global Drought Observatory (GDO) is used for determining the occurrence of long-term hydrological drought conditions, which arise when the TWS reaches values lower than usual. This quantity is often used as a proxy of groundwater drought. The TWS Anomaly indicator in GDO is computed as anomalies of GRACE-derived TWS data with respect to the long-term averege 2002-2022. TWS data are produced by the Center for Space Research (CSR) at the University of Texas at Austin, as scaled by the NASA Jet Propulsion Laboratory (JPL).
