Short summary
Freshwater stored on land is changing, but detailed global datasets of terrestrial water storage anomalies remain scarce. By combining satellite gravity observations with hydrological model outputs and glacier- and lake-defined mass concentration groups, we created a monthly high-resolution global dataset for April 2002 to December 2022. Tests show close agreement across river basins, better water-balance consistency in small basins, and better consistency with groundwater well observations.
