Abstract:

GRACE,launched in March 2003,measures spatio-temporal variations of the gravity field with an unprecedented resolution and precision. Jason1 measures the combined effect of steric and mass variations,while the former part can be inferred from GRACE and the latter from WOA05. The seasonal steric variations from difference between Jason1 and GRACE are compared with that of WOA05. The results show that CSR RL04,GFZ RL04 ,GRGS GL04 agree well with WOA05. Antarctic mass change rate distributions are estimated fr...

Key words: GRACE, Jason1, WOA05, steric sea level, Antarctic ice loss.
