Short summary
We have compared two methods of performing Absolute observations of the Earth's magnetic field. The newer, Residual method was evaluated for use at USGS geomagnetic observatories and compared with measurements using the traditional Null method. A mathematical outline of the Residual method is presented, including more precise conversions of the Declination angles to nanoTeslas (nT). Results show that the Residual method is better than the Null method, especially at high latitude.
