Welcome To IIG

The Indian Institute of Geomagnetism (IIG), Mumbai is a leading institute of the country, actively engaged in basic and applied research in Geomagnetism and allied areas of Geophysics, Atmospheric & Space Physics and Plasma Physics.

It started out as a successor to the Colaba Magnetic Observatory, set up in 1826, where the first regular magnetic observatory in the country was established in 1841.

In 1971 IIG became autonomous and is now under the Department of Science & Technology, Government of India.  

Area Of Research

The Indian Institute of Geomagnetism (IIG) is a premier institute of Department of Science & Technology and working on fundamental research on the geomagnetism and its allied fields.It had start working as a successor to the Colaba observatory which was established in 1826, which later in 1841 became the nation's first regular magnetic observatory research institute.

The current research activities of the institute are as follows:


Vision & Mission


To enable India to become a global knowledge power by promoting, guiding and conducting basic research in Geomagnetism and Allied fields.


To Promote, guide and conduct research in all branches of Geomagnetism. To build infrastructural support (using state-of-the-art technology) for acquisition of high quality data, leading to frontline research.

To maintain / modernize magnetic observatory network of India and establish new observatories and facilities at existing centers for other observations related to geomagnetism and allied fields.

To attract, motivate and train young talent to undertake research in geomagnetism.

IIG Observatory Instruments and Facilities

  The varied disciplines of research carried out by Indian Institute of Geomagnetism (IIG) encompass solid Earth geophysics, geophysics involving the atmospheric environment and space physics. A variety of instrument suites have been deployed by IIG at a number of sites, including permanent installations at its observatories across the length and breadth of the country and temporary sites in survey or campaign mode. IIG also offers consultancy services for measurements of geomagnetic field and related parameters at selected sites........ More
