r3d100010596 International Service of Geomagnetic Indices ISGI SIIG Service International des Indices Géomagnétiques http://isgi.unistra.fr/ FAIRsharing_DOI:10.25504/FAIRsharing.5Sfaz2 The International Service of Geomagnetic Indices (ISGI) is in charge of the elaboration and dissemination of geomagnetic indices, and of tables of remarkable magnetic events, based on the report of magnetic observatories distributed all over the planet, with the help of ISGI Collaborating Institutes. The interaction between the solar wind, including plasma and interplanetary magnetic field, and the Earth's magnetosphere results in a transfer of energy and particles inside the magnetosphere. Solar wind characteristics are highly variable, and they have actually a direct influence on the shape and size of the magnetosphere, on the amount of transferred energy, and on the way this energy is dissipated. It is clear that the great diversity of sources of magnetic variations give rise to a great complexity in ground magnetic signatures. Geomagnetic indices aim at describing the geomagnetic activity or some of its components. Each geomagnetic index is related to different phenomena occurring in the magnetosphere, ionosphere and deep in the Earth in its own unique way. The location of a measurement, the timing of the measurement and the way the index is calculated all affect the type of phenomenon the index relates to. The IAGA endorsed geomagnetic indices and lists of remarkable geomagnetic events constitute unique temporal and spatial coverage data series homogeneous since middle of 19th century. aude.chambodut@unistra.fr isgi@unistra.fr disciplinary 2013 eng 3 Natural Sciences 311 Astrophysics and Astronomy 315 Geophysics and Geodesy 31501 Geophysics 32 Physics 34 Geosciences (including Geography) http://isgi.unistra.fr/whats_isgi.php Raw data Scientific and statistical data formats Software applications Structured graphics Structured text dataProvider serviceProvider energy magnetic field magnetosphere solar terrestrial physics space sciences space weather CNRS-INSU Centre National de la Recherche Scientifique, Institut national des sciences de l'univers National Center for Scientific Research, National Institute for Earth Sciences and Astronomy FRA funding general sponsoring non-profit https://www.insu.cnrs.fr/node/1228 RRID:SCR_011247 RRID:nlx_98477 http://www.insu.cnrs.fr/contact Centre National d’Etudes Spatiales CNES FRA funding non-profit https://cnes.fr/en ROR:04h1h0y33 https://cnes.fr/fr/contactez-nous DTU Space Danmarks Tekniske Universitet, Space Institut for Rumforskning og-teknologi National Space Institute DNK general non-profit http://www.space.dtu.dk/English/ Wikidata:Q2570097 Ebro Observatory Observatori de l' Ebre ESP general non-profit http://www.obsebre.es/en/ ROR:03vht8z34 http://www.obsebre.es/en/contact Helmholtz Centre Potsdam - GFZ German Research Centre for Geosciences GFZ Helmholtz-Zentrum Potsdam Deutsches GeoForschungsZentrum DEU general non-profit https://www.gfz-potsdam.de/en/kp-index/ ROR:04z8jg394 ISPL-LATMOS Institut Pierrre Simon Laplace, Laboratoire Atmosphéres, Milieux, Observations Spatiales FRA technical non-profit http://www.latmos.ipsl.fr/index.php/fr/ 2009 2014 http://www.latmos.ipsl.fr/index.php/en/nous-contacter International Association of Geomagnetism and Aeronomy AIGA Association Internationale de Géomagnétisme et d'Aéronomie IAGA AAA general non-profit http://www.iaga-aiga.org/ Wikidata:Q6048492 http://www.iaga-aiga.org/index.php?id=imprinthtml International Council for Science, World Data System ICSU-WDS AAA general non-profit http://www.icsu-wds.org/ Russian Federal Service for Hydrometeorology and Environmental Monitoring, Arctic and Antarctic Research Institute, Department of geophysics ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ГИДРОМЕТЕОРОЛОГИИ И МОНИТОРИНГУ ОКРУЖАЮЩЕЙ СРЕДЫ, ФГБУ АРКТИЧЕСКИЙ И АНТАРКТИЧЕСКИЙ НАУЧНО-ИССЛЕДОВАТЕЛЬСКИЙ ИНСТИТУТ, Отдел Геофизики RUS general non-profit http://www.geophys.aari.ru/ pgc@aari.ru World Data Center for Geomagnetism, Kyoto JPN general non-profit http://wdc.kugi.kyoto-u.ac.jp/ École et Observatoire des Sciences de la Terre, Université de Strasbourg/CNRS-INSU Service national d’Observation en Magnétisme EOST School and Observatory of Earth Sciences, University of Strasbourg/CNRS-INSU National Service of Observation in Magnetism FRA funding general sponsoring technical non-profit http://eost.unistra.fr/ Wikidata:Q3577986 2015 http://eost.unistra.fr/contact/ Certification of WDS Members https://www.worlddatasystem.org/services/certification ICSU data policy https://www.worlddatasystem.org/services/data-sharing-principles Rules and Policy http://isgi.unistra.fr/policy.php open open CC https://creativecommons.org/licenses/by-nc/4.0/ other https://www.worlddatasystem.org/services/data-sharing-principles restricted other yes none http://isgi.unistra.fr/policy.php unknown yes WDS The 6 ISGI Collaborating Institutes are: EOST (Ecole et Observatoire des Sciences de la Terre, Strasbourg, France), GFZ (Helmholtz-Zentrum Potsdam Deutsches GeoForschungsZentrum Adolf-Schmidt-Observatorium, Potsdam, Germany), Observatori de l'Ebre (Roquetes, Spain), WDC Kyoto for Geomagnetism ( World Data Center for Geomagnetism, Data Analysis Center for Geomagnetism and Space Magnetism, Graduate School of Science, Kyoto University, Japan), DTU Space (DTU Space, National Space Institute, Lyngby, Denmark) and AARI (Arctic and Antarctic Research Institute, St.Petersburg, Russian Federation) [see: http://isgi.unistra.fr/collaborating_institutes.php].
