Abstract This paper presents the formula of the inverse Poisson integral, which is used for continuation of airborne gravity anomaly and to assess the accuracy of airborne gravity data. The downward continuation of airborne gravity data is performed by FFT and iterative methods. The accuracy is evaluated based on the comparison and analysis of downward continued results with terrestrial real gravity data. The choice of low-pass filters for downward continuation is also discussed. The experiment shows that the FFT method obtains better results compared with those derived from iterative methods.
