  • WMM2020 Released

    The latest World Magnetic Model (WMM2020) was released December 10, 2019. 

    The World Magnetic Model is the standard model for navigation, attitude and heading referencing systems using the geomagnetic field. The model, associated software, and documentation are distributed by NCEI on behalf of NGA. The model is produced at 5-year intervals, with the current model expiring on December 31, 2024.

  • Geomagnetism Story Map

    The CIRES geomagnetism team worked with the NCEI story map team to create an ArcGIS story map that takes users through all of the components of the Earth's magnetic field. Learn more about the magnetic field HERE

  • Geomagnetism XKCD

    The Earth's magnetic field changes over time, sometimes in ways we do not expect when we compile and release the model. That is why the geomagnetism team is updating the World Magnetic Model, so users can continue to navigate safely without noticing any performance issues. Credit XKCD

  • Crowdmag

    Use your phone as a magnetic sensor! Here is an opportunity for you to be a part of our research on the geomagnetic field. Install CrowdMag app and share your magnetic data. You can also view maps and graphs shared by other citizen scientists.

  • EMAG2_V3: Earth Magnetic Anomaly Grid 2 Arc-Minute Resolution Version 3

    The latest EMAG2 (v3) includes more than 11.5 M new ship and airborne trackline data, and several new or updated precompiled grids.  This version better represents the complexity of the lithosphere magnetic anomalies (particularly in oceanic regions) and accurately reflects areas where no data has been collected.

  • HDGM-RT

    The Real-Time add-on to the High Definition Geomagnetic Model (HDGM-RT) includes a model of Earth's magnetosphere which provides near real-time estimates of the external disturbance field due to the solar wind.  More Information

    The CIRES/NOAA Geomagnetism Team won the 2015 COLABS Governor's Award for High Impact Research for Magnetic Innovations: Pushing the Earth's Limits. Press Release

  • M2_Currents

    The background map illustrates the total scalar M2 magnetic field (a) amplitude and (b) phase predicted from the sum of the ionosphere and ocean sources. Each colored dot represents the total M2 scalar field amplitude and phase at a geomagnetic observatory.
