Table 3 Standard deviation (STD) of overall detrended time series of GAO, GRACE-based HAM/CAM (GSM, TWS, MAS land, and MAS global) and SLR-based HAM/CAM, errors of STD (STDerr), correlation coefficients (Corr) between HAM/CAM and GAO, percentage of variance in GAO explained by HAM/CAM (Varexp), root mean square error (RMSD) of HAM/CAM

From: Evaluation of hydrological and cryospheric angular momentum estimates based on GRACE, GRACE-FO and SLR data for their contributions to polar motion excitation
