Earth Magnetic Field Map. Using ground-based observatories, we provide continuous records of magnetic field variations; disseminate magnetic data to various governmental, academic, and private institutions; and conduct research into the nature of geomagnetic variations for purposes of scientific understanding and hazard mitigation. Earth's magnetic field — also known as the geomagnetic field — is generated in our planet's interior and extends out into space, creating a region known as the magnetosphere. Earth-Sun magnetic connectivity Models: Structure of Heliosphere Model: Density and magnetic field polarity in ecliptic plane Polarity: negative positive Planet positions: Magnetopause position and conditions at GOES satellites Model: Ionospheric potential, currents and polar cap Characteristics At any location, the Earth's magnetic field can be represented by a three-dimensional vector. Additional WMM uses include civilian applications, including navigation and heading systems. A typical procedure for measuring its direction is to use a compass to determine the direction of magnetic North. NOAA's National Centers for Environmental Information (NCEI), formerly the National Geophysical Data Center, and the collocated World Data Service for Geophysics, Boulder, operated by NOAA/NESDIS/NCEI, archive and make available geomagnetic data and information relating to Earth's magnetic field and Earth-Sun environment, including current declination, geomagnetic field models and magnetic.

Earth Magnetic Field Map. The study of Earth's past magnetism is called paleomagnetism. Data is organized into thematic categories click on one of the categories below to find data. These stripes are thought to been generated as rock cooled at. Magnetic anomaly maps and data for North America Airborne measurement of the earth's magnetic field over all of North America provides gridded data describing the magnetic anomaly caused by variations in earth materials and structure. Audience: High school, Higher education, Undergraduate, Non-majors, Higher education, Undergraduate, Majors, Higher. A report opens in a new window. Earth Magnetic Field Map.

Using ground-based observatories, we provide continuous records of magnetic field variations; disseminate magnetic data to various governmental, academic, and private institutions; and conduct research into the nature of geomagnetic variations for purposes of scientific understanding and hazard mitigation.

The model provides magnetic field values (total field, dip, and declination) at any point above or below Earth's surface.
