| 中文摘要 | Using observations registered with superconducting gravimeter GWR-C032 at station Wuhan, the tidal gravity parameters reflecting the characteristics of the Earth's interior medium are obtained based on the harmonic analysis after preprocessing of the raw data. Meanwhile the gravity loading is calculated using loading theory and a numerical integral convolution technique based on various global ocean tide models developed by methods of the altimetry technology and finite element method with consideration of tidal gauge data as constraints. The loading corrections are carried out to tidal gravity parameters in diurnal and semidiurnal wave bands respectively and the new ideal of the "loading correction effectiveness" is developed in order to investigate the adaptability of global ocean tide models. The numerical results show that the efficiencies of loading correction reach to 91% (O-1, NAO99) and 92% (M-2 , ORI96) for instance. The average efficiencies of the loading corrections obtained with 11 oceanic models for four main constituents (O-1 K-1 , M-2 and S-2) are given as 86%, 70%, 73% and 84% respectively. And the discrepancies between the amplitude factors and the theoretical values decrease from (2.12%, 1.55%, 1.16% and 0.80%) to (0.31%, 0.39%, 0.34% and 0.08%) respectively. The comparison among various ocean models shows also that the efficiency of the loading correction when using NAO99 and ORI96 models is higher than that when using other models. Additionally, other observations obtained with superconducting gravimeters at seven stations in a network of the Global Geodynamic Project are also adopted to investigate the adaptability of the global ocean models. The results show that there exist obvious local tidal characteristics for different constituents in different ocean models and the earlier constructed SCW80 ocean model can still be used as an important reference in geodesy research domain. |
