The 12th generation of the International Geomagnetic Reference Field (IGRF) was adopted in December 2014 by Working Group V-MOD appointed Association Geomagnetism and Aeronomy (IAGA). It updates previous IGRF with a definitive main field model for epoch 2010.0, 2015.0, linear annual predictive secular variation 2015.0-2020.0. Here, we present equations defining model, provide spherical harmonic coefficients, maps magnetic declination, inclination, total intensity 2015.0 their predicted rates...
Swarm, a three-satellite constellation to study the dynamics of Earth’s magnetic field and its interactions with Earth system, is expected be launched in late 2013. The objective Swarm mission provide best ever survey geomagnetic temporal evolution, order gain new insights into system by improving our understanding interior environment. In derive advanced models (and other higher-level data products) it necessary take explicit advantage aspect Swarm. SCARF (SatelliteConstellationApplication...
Abstract The eastward equatorial electric field (EEF) in the E region ionosphere drives many important phenomena at low latitudes. We developed a method of estimating EEF from magnetometer measurements near‐polar orbiting satellites as they cross magnetic equator, by recovering clean signal electrojet current and modeling observed to determine present during satellite pass. This algorithm is now implemented an official Level‐2 Swarm product. Here we first results estimates nearly year data....
The day-time eastward equatorial electric field (EEF) in the ionospheric E-region plays a crucial role dynamics. It is responsible for driving electrojet (EEJ) current system, vertical ion drifts, and ionization anomaly (EIA). Due to its importance, there much interest accurately measuring modeling EEF both climatological near real-time studies. Swarm satellite mission offers unique opportunity estimate from measurements of geomagnetic field. near-polar orbits each satellite, on-board...
The geomagnetic daily variation at mid-to-low latitudes, referred to as the Sq field, is generated by electrical currents within conducting layers of ionosphere on dayside Earth. It enhanced in a narrow equatorial band, due electrojet. upcoming ESA Swarm satellite mission, be launched end 2013, will consist three satellites low-Earth orbit, providing dense spatial and temporal coverage ionospheric field. A Satellite Constellation Application Research Facility (SCARF) has been set up...
Abstract European Space Agency's Swarm satellites carry a new generation of 4 He absolute magnetometers (ASM), designed by CEA‐Léti and developed in partnership with Centre National d'Études Spatiales. These instruments are the first ever spaceborne to use common sensor simultaneously deliver 1 Hz independent scalar vector readings magnetic field. Since launch, these ASMs provided very high‐accuracy field data, as nominally required for mission, together experimental data. Here we compare...
The forthcoming Swarm satellite mission is a constellation of three satellites dedicated to the study geomagnetic field. orbital characteristics mission, which includes pair flying side by side, has prompted new efforts in data processing and modeling. A consortium several research institutions been selected European Space Agency (ESA) provide number Level-2 products will be made available scientific community. Within this framework, specific tools have tailor-made better recover...
Abstract Each of the three satellites European Space Agency Swarm mission carries an absolute scalar magnetometer (ASM) that provides nominal 1-Hz data for both science and calibration purposes. These ASM instruments, however, also deliver autonomous experimental vector data. Here, we report on how ASM-only from Alpha Bravo between November 29, 2013 (a week after launch) September 25, 2014 (for on-time delivery model October 1, 2014) could be used to build a very valuable candidate 2015.0...
Abstract The GEOSCOPE observatory (Institut de physique du globe Paris [IPGP] and École et Observatoire des Sciences la Terre Strasbourg, 1982) provides more than four decades of high-quality continuous broadband data to the scientific community. Started in 1982 with only two stations, network has grown over years thanks numerous international partnerships. At present, 34 stations operate 18 countries across all continents on islands throughout oceans, filling important gaps global Earth...
The GEOSCOPE observatory provides more than 4 decades of high-quality continuous broadband data to the scientific community. Started in 1982 with a few stations, network has grown over years thanks numerous international partnerships. 33 operational stations are now installed 18 countries, across all continents and on islands throughout oceans, filling important gaps global Earth coverage (in Africa, Antarctica, Indian Ocean, Pacific Ocean more). Most first still running today allowing for...
