摘要
为完善深层地球结构和跟踪地球表面的质量变化,结合GRACE重力卫星在高精度地球重力场时变信号观测中的优势,基于GRACE重力卫星数据进行了相应的研究。通过极地高山冰川、地震研究、地球重力场模型反演以及水文应用等方面,概括了GRACE重力卫星及其数据产品的应用现状,归纳了影响GRACE数据反演精度的误差来源并给出相应的处理方法与建议,最后对GRACE卫星数据的深入应用问题进行了讨论和总结,旨在为后续相关应用研究提供一定参考价值。
In order to improve the structure of the deep earth and track the change of the surface quality of the earth,combined with the advantage of GRACE gravity satellite in the observation of high-accuracy earth gravity field,the corresponding research have been made based on the GRACE gravity satellite data. This paper summarized the application status of GRACE satellite and its data products through several aspects like the polar alpine glaciers,earthquakes,earth gravity field inversion and hydrology etc. o,the error sources affecting the inversion accuracy of GRACE data are summarized and the corresponding processing method and advises are given. Finally,the problem of the further application of GRACE gravity satellite data are discussed and summarized,which has a certain reference value for the follow-up research.
