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.

Research And Update

Numerical Simulations:
(This is test)One-dimensional fluid and particle codes have been developed to study non-linear waves and instabilities in the Solar wind - Magnetosphere - Ionosphere coupled system. Currently the two-dimensional fluid and particle codes are being developed.

Impact of severe solar flare on Ionosphere
An attempt is being made to study the impact of severe solar flare on the electrodynamics of the equatorial and low latitude ionosphere using Global Positioning System (GPS) receiver, Canadian Advanced Digital Ionosonde (CADI) observations and Very low frequency (VLF) observations at IIG stations.

composite magnetic anomaly map of india
IIG is actively involved in the preparation of a composite magnetic anomaly of the country and adjoining areas integrating magnetic data collected from ground, airborne, shipborne and satellite platforms. This map will prove useful for structural and geological mapping, locating areas conducive for mineral and oil exploration etc. First generation of this map was brought out in 2006 (Rajaram et al, JGSI). A proxy heat flow map the country utilizing data from Champ satellite has recently been generated that depicts areas of high geothermal gradients.
