联合多种测高数据确定中国海及其邻域1.5′×1.5′重力异常

Gravity Anomalies with Resolution of 1.5′×1.5′Over China Sea and Its Vicinity Derived from Multi-Satellite Altimeter

    摘要
  • 摘要: 联合多种测高资料和Geosat/GM波形重构数据,基于EIGEN_CG01C重力场模型,采用沿轨迹加权最小二乘方法和逆Vening-Meinesz公式,确定了中国海及其邻域1.5′×1.5′重力异常。将计算结果与最新船测资料进行了比较,标准差为3.37×10-5m.s-2。

     

    Abstract: On the basis of gravity field model(EIGEN_CG01C),together with multi-altimeter data,the improved gravity anomalies gridded in 1.5′×1.5′ in China sea and vicinity are determined using the weighted method of along-track least squares and inverse Vening-Meinesz formula.Compared with the shipboard gravimetry in South China Sea;the results show that the accuracy of the gravity anomalies computed with the altimeter data is 3.37×10-5 m·s-2.
