About Indian Institute of Geomagnetism

Indian Institute of Geomagnetism ( IIG ) , Navi Mumbai is a premier Research Organization functioning under the Department of Science and Technology (DST) of Govt. of India as an autonomous research institute since 1971. It has a mandate to carry out research in all aspects of the Science of Geomagnetism. The Institute is a successor to the world renown COLABA-ALIBAG Magnetic Observatory which has been functioning since 1841. The development of geomagnetism in the country is always associated with the growth and evolution of this Institution.

TheThe major activities of the Institute are divided in three main Research Areas.

  • Observatory and Data Analysis
  • Upper Atmospheric Science
  • Solid Earth Geomagnetism

Magnetic Observatory Network

IIG operates a network of Ten Magnetic Observatories in the Indian longitude chain encompassing the stations from Magnetic equator to the location of the focal latitude of the low latitude Sq current system. Variations in the geomagnetic field are recorded continuously at these observatories, which extend from dip equator to the northernmost latitude of India. These observatories are also covering both the west and east coasts. The data and records generated at all these observatories are collected at the Observatory & Data Analysis ( ODA ) division stationed at the Headquarter in Navi Mumbai.

Antarctic Program :-
      IIG has been an integral part of the National Antarctic Program right through its inception. Antarctic Geomagnetism has special importance for India in the sense that Maitri (MAI) and Dakshin Gangotri (DG) (both located at about 700 South, 120 East geographic) are the only locations where India can carry out research on high-latitude geomagnetism.
