to estimate the values of a
gravitational or
magnetic field
A magnetic field (sometimes called B-field) is a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular ...
by using measurements at a lower elevation and extrapolating upward, assuming
continuity. This technique is commonly used to merge different measurements to a common level so as to reduce scatter and allow for easier analysis.
