International Association of Geomagnetism and Aeronomy
Encyclopedia
International Association of Geomagnetism and Aeronomy (IAGA) is the premier international scientific association promoting the study of terrestrial and planetary magnetism
and space physics
.
IAGA is one of the eight Associations of the International Union of Geodesy and Geophysics
(IUGG). It is a non-governmental body funded through the subscriptions paid to IUGG by its Member Countries. IAGA has a long history and can trace its origins to the Commission for Terrestrial Magnetism and Atmospheric Electricity, part of the World Meteorological Organization
originated from the International Meteorological Organization
(IMO), which was founded in 1873. At the First IUGG General Assembly (Rome, 1922), the Section de Magnétisme et Electricité Terrestres became one of the constituent sections of the Union. At the IV IUGG General Assembly (Stockholm, 1930), it became the International Association of Terrestrial Magnetism and Electricity. It took its present name at the X IUGG General Assembly (Rome, 1954).
IAGA is subdivided into the following Divisions and Commissions with working groups on subjects of interest:
Magnetism
Magnetism is a property of materials that respond at an atomic or subatomic level to an applied magnetic field. Ferromagnetism is the strongest and most familiar type of magnetism. It is responsible for the behavior of permanent magnets, which produce their own persistent magnetic fields, as well...
and space physics
Physics
Physics is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.Physics is one of the oldest academic...

International Union of Geodesy and Geophysics
The International Union of Geodesy and Geophysics is a non-governmental organisation dedicated to the scientific study of the Earth using geophysical and geodesic techniques. The IUGG was established in 1919. Some areas within its scope are environmental preservation, reduction of the effects of...

International Meteorological Organization
The International Meteorological Organization was the first organization formed with the purpose of exchanging weather information among the countries of the world. It was born from the realization that weather systems move across country boundaries and knowledge of pressure, temperature,...

IAGA is subdivided into the following Divisions and Commissions with working groups on subjects of interest:
- Division I: Internal Magnetic Fields

- Division IV: Solar Wind and Interplanetary Field
- Division V: Geomagnetic Observatories, Surveys, and Analyses
- Interdivisional Commission on History
- Interdivisional Commission on Developing Countries
- International Service of Geomagnetic Indices
