基于Grace月重力场模型的稳态地球重力场模型分析OACSTPCD
Stable Analysis on the Monthly GRACE Gravity Model
基于106个月的Grace( gravity recovery and climate experiment)月重力场模型(120阶次),消除了月重力场的月、季度及年度变化,得到了稳态的地球重力场模型(Grace_sta).在2～120阶次之间,Grace_sta与已有高阶重力场EGM2008及EGM96 三个模型的阶方差是一致的.在2～100阶次之间,Grace_sta模型误差阶方差要小于EGM2008与EGM96误差阶方差.在全球范围内,Gr…查看全部>>
A stable earth gravity model with high precision(Grace_sta)was obtained based on 106 months continual Grace(gravity recovery and climate experiment)model,whose spherical harmonic degree and order was 120,after eliminating the monthly,quarterly and annual variations. Among the degree 2 ～ 120,the degree variance curve of Grace_sta model was consistent with the EGM2008 and EGM96. But the error degree variance of the former was better than the latter two models …查看全部>>
