A number of corrections are applied to measured gravity data in the field before contouring the Bouguer gravity anomaly map and then deducing a model of the anomalous body that may be causing the anomaly. One such correction is known as the `free-air correction'. The free-air correction term given in many textbooks, for example, Introduction to Geophysical Prospecting by Dobrins, is of the form (2 h g0/R), where h is the height of the grid point above the mean sea level, R is the radius of the Earth and g0 is the Earth's total gravity field, from the reference ellipsoid. This is in fact a correction to the whole Earth effect. What is not normally included in this type of calculation is the free-air correction for that component of the Earth's field caused by the anomalous body, Δg.
