Geomagnetic Observatories at Australian Antarctic and subantarctic stations

Geomagnetic Observatories at Mawson and Macquarie Island, magnetic secular variation information from Davis and Casey, magnetic repeat stations in AAT and Heard Is (former observatories Wilkes, Heard).The geomagnetic elements X, Y and Z are the components of the vector field in the Geographic North, Geographic East and Vertical directions. They are in a cartesian coordinate system. The magnetic field is completely defined by three independent components such as X,Y and Z. It can also be expressed in polar coordinates as D,F,I where D is the declination, I is the inclination and F is the magnitude of the vector field. There is one other component used: H. This is the horizontal component. H,D and Z or D,H and F are also commonly used to define the magnetic field.Data stored at Geoscience Australia (GA).This is part of ASAC project 760.The fields in this dataset are:DateX (nT)Y (nT)Z (nT)
