[期刊论文] 作者：Jim Ray,Paul Rebischung,Jake Griffiths,,
来源：Geodesy and Geodynamics 年份：2017
We elaborate an error budget for the long-term accuracy of IGS(International Global Navigation Satellite System Service) polar motion estimates, concluding that it is probably about 25-30 μas(1-sigma)...

Geophysical excitations of length-of-day(LOD) variations is of great significance in understanding changes in the Earths spin rate and interactions between geophysical fluids and the solid Earth,as we...
Improved geophysical excitations constrained by polar motion observations and GRACE/SLR time-depende
[期刊论文] 作者：Wei Chen,Jiancheng Li,Jim Ray,Minkang Cheng,,
来源：Geodesy and Geodynamics 年份：2017
At seasonal and intraseasonal time scales, polar motions are mainly excited by angular momentum fluctuations due to mass redistributions and relative motions in the atmosphere, oceans, and continental...
