| Abstract: | The ability of GRACE to inverse the global seawater mass variations is estimateed and by combining satellite altimetry with GRACE the global SSL(Steric Sea Level) variation for three years(from Jan. 2003 to Dec. 2005)is calculated. The conclusion that GRACE not only can observe the seasonal ocean mass variations, but also the combination of GRACE with altimetry can provide an ESSL(Estimated SSL) that is closer to SSL than using altimetry alone is drawn. |
