Abstract
The writer has tested most of the available methods for the upward continuation of the gravity anomaly in a previous work. In this present paper he adds two new methods, the modified statistical method and the empirical method, for low elevations. The two developed methods are based on the upward continuation integral. A simple template is suggested to be used with each method. The two methods were tested in Ohio for elevations 5, 10, and 15 km. Their results were compared with those obtained by using Hirvonen's template. A comparison between the standard errors of the results from different methods proves that the new methods are not only simpler than the others, but also more accurate.
