| Abstract: | In this paper. one brief Smoothing factor in calculation of mean gravity anomolies has been given. and it has been compared with the Colombo's smoothing factor. The difference shows that the accuracies of two factors are the very same. Finally. it has been compared with its relevant one obtained by integration. The difference between them shows the error of calculation of mean gravity anomalies is less than 1 mgal in our country. |
