Variations of Earth Rotation and Geopotential

According to the development of determination of geopotential by space geodesy, a combined method using Earth rotation parameters and low degree harmonic coeffcients of geopotential determined by space geodesy is suggested to study the variation of Earth angular momentum. The prominent advantage of this method is that the Earth angular momentum can be decoupled into mass term and velocity term and hence makes a complex problem simplified. As an example of our method, the Lageos-1 and Lageos-2 SLR data are used to obtain the time series of ΔC 20. A good agreement can be achieved between the computed ΔLOD series using C 20 and the (ΔLOD-Wind) residual series, which indicates the effectiveness of our method.
