International Real-time Magnetic Observatory Network
The International Real-time Magnetic Observatory Network (INTERMAGNET) is a world-wide consortium of institutes operating ground-based magnetometers recording the absolute level of the Earth's time-varying magnetic field, to an agreed set of standards. INTERMAGNET has its roots in discussions held at the Workshop on Magnetic Observatory Instruments in Ottawa, Canada, in August 1986 and at the Nordic Comparison Meeting in Chambon La Foret, France, in May 1987. A pilot scheme between USGS and BGS was described in the sessions of Division V of the International Association of Geomagnetism and Aeronomy at the 19th General Assembly of the International Union of Geodesy and Geophysics in Vancouver, Canada, in August 1987. This scheme used the GOES East satellite to successfully transfer geomagnetic data between the two organisations. INTERMAGNET was founded soon after in order to extend the network of observatories communicating in this way. 62 different institutes are now members of t ...

Earth's Magnetic Field
Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from structure of Earth, Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun. The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo. The magnitude of Earth's magnetic field at its surface ranges from . As an approximation, it is represented by a field of a magnetic dipole currently tilted at an angle of about 11° with respect to Earth's rotational axis, as if there were an enormous bar magnet placed at that angle through the center of Earth. The North geomagnetic pole (Ellesmere Island, Nunavut, Canada) actually represents the South pole of Earth's magnetic field, and conversely the South geomagnetic ...

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

British Geological Survey
The British Geological Survey (BGS) is a partly publicly funded body which aims to advance Earth science, geoscientific knowledge of the United Kingdom landmass and its continental shelf by means of systematic surveying, monitoring and research. The BGS headquarters are in Keyworth, Nottinghamshire, England. Its other centres are located in Edinburgh, Wallingford, Oxfordshire, Wallingford, Cardiff and London. The current tagline of the BGS is: ''Understanding our Earth''. History and previous names The Geological Survey was founded in 1835 by the Board of Ordnance as the Geological Survey of Great Britain, under Directors of the British Geological Survey, directorship of Henry De la Beche. This was the world's first national Geological Survey, geological survey. It remained a branch of the Ordnance Survey for many years. In 1965, it was merged with the Geological Museum and Overseas Geological Surveys, under the name of Institute of Geological Sciences. In 1969, Beris Cox was ...

ISC World Data System
The World Data System (WDS) was created by the International Council for Science (ICSU), the predecessor to the International Science Council (ISC), at their 29th General Assembly in October 2008. The mission of the World Data System is to enhance the capabilities, impact and sustainability of member data repositories and data services by creating trusted communities of scientific data repositories, strengthening the scientific enterprise throughout the entire lifecycle of all data related components - creating first-class data that feeds first-class research output, and advocating for accessible data and transparent and reproducible science. The World Data System consists of two offices: the International Program Office (IPO) in Oak Ridge, Tennessee, United States, and the International Technology Office (ITO) in Victoria, Canada. Historical Background WDS builds on the 50+ years legacy of the World Data Centers and Federation of Astronomical and Geophysical Data Analysis Se ...

International Science Council
The International Science Council (ISC) is an international non-governmental organization that unites scientific bodies at various levels across the social and natural sciences. The ISC was formed with its inaugural general assembly on 4 July 2018 by the merger of the former International Council for Science (ICSU) and the International Social Science Council (ISSC), making it one of the largest organisations of this type. Daya Reddy, mathematician, served (2018–2021) as the ISC's inaugural President. Sir Peter Gluckman, pediatrician, biomedical scientist, and science-policy expert, was elected President in October 2021. Other ISC's inaugural Officers elected for the term of 2018–2021 were Elisa Reis (Vice President), Jinghai Li (Vice President), Renée van Kessel (Treasurer), and Alik Ismail-Zadeh (Secretary).

International Geomagnetic Reference Field
The International Geomagnetic Reference Field (IGRF) is a standard mathematical description of the large-scale structure of the Earth's main magnetic field and its secular variation. It was created by fitting parameters of a mathematical model of the magnetic field to measured magnetic field data from surveys, observatories and satellites across the globe. The IGRF has been produced and updated under the direction of the International Association of Geomagnetism and Aeronomy (IAGA) since 1965. The IGRF model covers a significant time span, and so is useful for interpreting historical data. (This is unlike the World Magnetic Model, which is intended for navigation in the next few years.) It is updated at 5-year intervals, reflecting the most accurate measurements available at that time. The current 13th edition of the IGRF model (IGRF-13) was released in December 2019 and is valid from 1900 until 2025. For the interval from 1945 to 2015, it is "definitive" (a "DGRF"), meanin ...

Space Weather
Space weather is a branch of space physics and aeronomy, or heliophysics, concerned with the varying conditions within the Solar System and its heliosphere. This includes the effects of the solar wind, especially on the Earth's magnetosphere, ionosphere, thermosphere, and exosphere. Though physically distinct, space weather is analogous to the terrestrial weather of Earth's atmosphere of Earth, atmosphere (troposphere and stratosphere). The term "space weather" was first used in the 1950s and popularized in the 1990s. Later, it prompted research into "space climate", the large-scale and long-term patterns of space weather. History For many centuries, the effects of space weather were noticed, but not understood. Displays of aurora (astronomy), auroral light have long been observed at high latitudes. Beginnings In 1724, George Graham (clockmaker), George Graham reported that the needle of a magnetic compass was regularly deflected from magnetic north over the course of each day. ...
