Accuracy Analysis of the Remove-Restore Process in Inverse Stokes Formula

The remove-restore process essentially is to replace the data outside the observed area on Earth with some known model.But in practical application,there are some problems needed to be studied when the remove-restore process is applied.For example,how to determine the integral domain and to evaluate the accuracy Firstly,this paper gives a new derivation of inverse stokes formula,and then concretely analyze and discuss the accuracy of the remove-restore method in order to research the source of error in actual computation.Combined with the accuracy problem,we focus on analyzing size of the integral domain and the number of the removed degree and obtain several useful conclusions.
