Abstract

By Degree-1 deformation approach,this paper inverses geocenter motion using reprocessed IGS weekly solution from 2000 to 2009.Results shows that annual amplitudes are 3.72 mm,3.06 mm and 8.95 mm in X,Y and Z direction respectively.And the maximum mass load within northern hemisphere is during February,and that of southern hemisphere is during August.
