N2  - A simple technique is described for removing residual levelling errors from aeromagnetic data. These residual errors have a distinct spectral signature and are easily removed from a grid of the data using existing directional grid-filtering methods. The filtered grid is then used to correct the located data. The method can not distinguish between levelling errors and real elongate anomalies parallel to the flight-line direction. It should therefore be used selectively.
