The Earth's magnetic field strength was measured by Carl Friedrich Gauss in 1832 and has been repeatedly measured since then, showing a relative decay of about 10% over the last 150 years. The Magsat satellite and later satellites have used 3-axis vector magnetometers to probe the 3-D structure of the Earth's magnetic field. The later Ørsted satellite allowed a comparison indicatin… WebNOAA's National Centers for Environmental Information and the collocated World Data Centers, Boulder, operated by NOAA/NESDIS/NCEI, archive and make available geomagnetic data and information relating to Earth's … binance google authenticator silindi

WebFeb 2, 2015 · A new version of the International Geomagnetic Reference Field (IGRF), the international standard description of the Earth's magnetic field, has been announced this month. The Division of Geomagnetism at DTU Space have played a key role in the new IGRF model, which is largely based on magnetometer data from the Swarm mission.
