Short summary
Existing correction methods may introduce large errors, and more seriously cause unrealistic negative values in P, ET and Q in up to 10 % of cases. A novel IWE-Res method is proposed to improve the accuracy and consistency of corrected satellite-based water budget component data. In most river basins (except cold regions), the best correction is achieved by adjusting 40 % to 90 % of the total water imbalance error.
