| 中文摘要 | With the advent of the satellite gravity measurements, this new technique which is different from. Satellite Laser Ranging (SLR) provides a new approach to determine the Earth's. Dynamic Ellipticity : (EDE). The Gravity Recovery and Climate Experiment (GRACE) is the latest satellite gravity mission; the accuracy of low degree Stokes coefficients. of the gravity field models derived from GRACE has been greatly improved.: However, the results of EDE from,GRACE do not agree well with that from SLR measurements. In this paper, the maximum entropy spectral analysis and wavelet:analysis are used to assess the data sets EDE from GRACE and SLR. The results show that the interannual amplitude of the EDE signal from GRACE is only 25% of that from SLR, and GRACE EDE signals contain inputted system information and great phase difference, but the former reveals' stronger short-term (2 similar to 6 months) `signals than the later. These, differences might be caused by the un-synchronism of the global measurements from GRACE and SLR. |
