Abstract: 介绍了在香港地区重力固体潮合作观测成果,获得了该地区完整的重力固体潮实测模型.利用全球和近海海潮模型以及岛屿验潮站数据较系统地研究了海潮负荷特征,反演了全球海潮模型的适定性.数值结果说明周日频段内的海潮模型要比半日频段内的模型更加稳定,实施验潮站潮位高变化改正对精密确定重力固体潮相位滞后起重要作用.文章还研究了重力观测残差和台站背景噪声水平.本项研究填补了中国地壳运动观测网络在该地区重力固体潮观测空白,为地表和空间大地测量提供有效参考和服务.
The tidal gravity observation achievements obtained in Hong Kong area are presented,the first complete tidal gravity experimental model in this area is obtained.The ocean loading characteristics are studied systematically by using global and local ocean models as well as tidal gauge data,the suitability of global ocean models is also studied.The numerical results show that the ocean models in diurnal band are more stable than those in semidiurnal band,and the correction of the change in tidal height plays a significant role in determining accurately the phase lag of the tidal gravity.The gravity observation residuals and station background noise level are also investigated.The study fills the empty of tidal gravity observation in the Crustal Movement Observation Network of China and can provide the effective reference and service to ground surface and space geodesy.
