  • 摘要: 重力场是反映地球介质密度变化和在各种环境(固体地球潮汐、内部热流、固体和液体之间质量的交换、表面负荷和地震构造运动等)下动力学特征的最基本和最直接的物理量。GRACE(Gravity Recovery and Climate Experiment)卫星作为探测全球重力场的工具已经为科研工作者提供了超过10 a的全球时变重力场数据。由于GRACE数据存在固有误差,GRACE数据产品需要进行后处理对局部重力场进行研究。回顾整理了GRACE数据后处理中的处理方法,包括高斯滤波法及非各向同性滤波法,位系数去相关法,主成分分析法,小波分解法,Slepian方法,以及顾及先验信息的改进算法等,并对GRACE后处理算法的后续改进和发展进行了展望。

摘要: 重力场是反映地球介质密度变化和在各种环境(固体地球潮汐、内部热流、固体和液体之间质量的交换、表面负荷和地震构造运动等)下动力学特征的最基本和最直接的物理量。GRACE(Gravity Recovery and Climate Experiment)卫星作为探测全球重力场的工具已经为科研工作者提供了超过10 a的全球时变重力场数据。由于GRACE数据存在固有误差,GRACE数据产品需要进行后处理对局部重力场进行研究。回顾整理了GRACE数据后处理中的处理方法,包括高斯滤波法及非各向同性滤波法,位系数去相关法,主成分分析法,小波分解法,Slepian方法,以及顾及先验信息的改进算法等,并对GRACE后处理算法的后续改进和发展进行了展望。
