Correction Problem of the Ocean Loading Signals to Strain Field Variation at Foundational Stations in Crust Movement Observation Network in China

利用最新的卫星测高全球海潮Csr3.0模型 ,中国近海海潮数据和标准地球模型负荷格林函数 ,采用直接褶积积分方法研究中国地壳运动观测网络基准站应变固体潮观测的海潮负荷影响。计算 2 5个台站 8个主要潮波的负荷振幅和相位 。

The influence of the ocean loading on strain earth tidal observation at foundational stations in crust movement observation network in China is studied by using a direct convolution integral method with consideration of the most recent global ocean models Csr3.0 obtained using satellite altimeter technique, the ocean tidal models along the coast of China and the standard Earth model Green's functions. The loading amplitudes and phases of 8 main waves at 25 stations are calculated, the characteristics of the strain loading flowers and of the temporal variation of the strain loading at several main stations are discussed in this paper.
