Calculation and Accuracy Estimation of Marine Mean Free-Air Gravity Anomaly

More Information
  • Received Date: March 04, 1995
  • Published Date: April 04, 1995
  • This paper presents a new method of interpolating gravity anomaly mean process with aximuth and distance as weight.And the gradient of gravity anomaly is proposed to be used as the criterion of mean anomaly accuracy.Then,the relation between gravity gradient and mean anomaly accuracy is established through the geopotential model OSU91A.Finally,the accuracies of marine mean free-air gravity anomalies are estimated with the relation.
