GDO Total Water Storage Anomaly (TWSA) (GRACE) (version 1.2.0)

Collection: DROUGHT : Drought Observatories datasets 

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).
