Fig. 7From: Development of a Synthetic Earth Gravity Model by 3D mass optimisation based on forward modellingThe optimised mass layer (a) after 389 iteration steps with the height increments of Table 1 used. Effect on the synthetic geoid height N (b) caused by the optimised mass layer. (c) The optimised synthetic Earth gravity model expressed in geoid height N. Remaining geoid height differences (d) between the optimised SEGM and EGM2008 (Robinson projection).Back to article page
