(a) Simulated mass layer after the first iteration step with a height increment of 500 m. (b) Difference between the synthetic geoid heights of the optimised SEGM and EGM2008 after the first iteration step. RMS value: ±87 m. (c) Simulated mass layer after the 100th iteration step with a height increment of 100 m. (d) Difference between the synthetic geoid heights of the optimised SEGM and EGM2008 after the 100th iteration step. RMS value: ±5.4 m (Robinson projection).
