Differential Reduction to the Pole

H005 DIFFERENTIAL REDUCTION TO THE POLE 1 Summary Due to the dipolar nature of the geomagnetic field magnetic anomalies located anywhere other than at the magnetic poles are asymmetric even when the magnetic source distribution is symmetrical. This complicates interpretation. Pole reduction (RTP) takes the anomaly as measured at any latitude and transforms it into that which would have been measured if the body had lain at the magnetic pole i.e. the area where the inclination is vertical and the anomalies from symmetrical bodies are symmetrical. The algorithm is usually applied in the frequency domain. This has the advantage of
