Abstract : A Statistical Method for Upward and Downward Continuation of Gravity. By replacing the actual gravity anomaly function by a suitable statistical model, it is possible to obtain a function of elevation H so that multiplying any free air gravity anomaly at ground by this function yields an approximate value for the corresponding gravity anomaly at height H. This method which has been tested numerically, can be applied for upward and downward continuation of gravity. Another method for downward continuation is sketched. On the Arrangement of Gravity Stations for Upward Continuation. For moderate elevations, especially for airborne gravimetry, the influence of the arrangement of gravity station and of the neglected outer zones is estimated. Based on this, a specific arrangement is proposed. (Author)
