摘要：

Key Points GRACE-derived global ocean mass change agrees remarkably well with Altimeter-Argo estimates at both seasonal and long-term scales Appropriate implementation of global mass conservation is important in GRACE global mean ocean mass change estimation Retaining GRACE Delta J(2) coefficients provides better GRACE ocean mass estimates at both seasonal and long-term scales
