Downscaling GRACE total water storage data using random forest: a three-round validation approach under drought conditions

Downscaling GRACE total water storage data using random forest: a three-round validation approach under drought conditions

The application of GRACE satellite-derived Total Water Storage (TWS) data for local water management is constrained by its coarse spatial resolution (100-300 km). To address this limitation, a Random Forest-based model was employed to downscale GRACE TWS data from 100 km to 1 km resolution over Moro...
