The remaining value of gravitational attraction after accounting for the
theoretical gravitational attraction at the point of measurement, latitude, elevation, the
Bouguer correction and the
free-air correction (which compensates for height above sea level assuming there is only air between the measurement station and sea level). This
anomaly is named for Pierre Bouguer, a French mathematician (1698 to 1758) who demonstrated that gravitational attraction decreases with altitude.
