Requirements for Gravity Data Within the Given Accuracy of the Interpolated Gravity Anomaly

  • 摘要: 基于最小二乘配置误差估计公式,建立了重力异常格网数据的分辨率和精度与重力异常内插值精度的关系,提出了在给定插值精度时反推已知格网数据的分辨率和精度的方法。以EGM2008重力场模型为例,在不同分辨率和精度条件下进行重力异常插值实验。实验结果与本文方法的计算结果基本一致,表明该方法具有一定的可行性。

     

    Abstract: To deduce required resolution and accuracy of grid data from the interpolation error of gravity anomaly is a typical inverse problem.Based on the error estimation formula of least squares collocation,the contribution of the resolution and accuracy of grid data to the interpolation error is discussed.A method is proposed to determine the necessary resolution and accuracy when the interpolation error is given.To assess the method,interpolation experiments are performed using EGM2008 gravity data with various resolution and accuracy.The results are consistent with those derived by the method proposed in this paper,which validates the feasibility of the method.
