However, the overlying positive EGM-96 free-air anomaly suggests that the crustal model may not be completely compensated.
Free-air anomaly, [DELTA]g, which in a modern context (proposed in Molodenskij 1945) is defined as the difference between the actual gravity measured on the topographic surface g([r.
The free-air anomaly is known to be highly correlated with the heights of the topographic masses, so, if there is rough topography in the computation area, the free-air anomalies will be rough as well.
11187H Hence, the Bouguer anomaly can be calculated via free-air anomaly and height:
The free-air anomaly is known to be more sensitive to the topography, so, if there are rough topographic masses in the computation area, the free-air anomalies will be rough and that is why the interpolation cannot always be successful.
The free-air anomaly can be calculated from the geopotential model by the series
