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:

  • Division I: Internal Magnetic Fields
  • Division II: Aeronomic Phenomena
  • Division III: Magnetospheric Phenomena
  • 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
