Magnetic Observatories and Data Analysis

The geophysical discipline of geomagnetism carries out scientific study of the Earth’s external and internal field comprising secular change, and magnetic reversals. This is a multidisciplinary science and magnetic observatories (MOs) provide data to those institutes, whose interests range from geology, subsurface structural mapping, geophysics (including seismology and earthquake prediction), meteorology, solar-terrestrial physics, and astronomy. Most of the surface magnetic phenomena exhibit strong dependence on both latitude and longitude. A worldwide network of magnetic stations is, therefore, absolutely essential for continuous monitoring of the ionospheric and magnetospheric phenomenon. Much depends on the accuracy and stability of the input magnetic data from magnetic observatories.
