Australian geomagnetic reference field 1985



The Australian Geomagnetic Reference Field (AGRF) is being developed as a set of epoch models of Earth's magnetic field and its secular variation (SV) over Australia and the surrounding region, including Indonesia, Papua New Guinea, the southwestern Pacific Ocean, and New Zealand. The AGRF model for 1985 is based on information from eight magnetic observatories and 122 repeat stations: 65 in Australia and its offshore islands, 28 in Indonesia, six in Papua New Guinea, three on islands elsewhere in the southwest Pacific, and 20 in New Zealand and its offshore islands.
