NCEI's aeromagnetic program provides global data to support modeling of Earth's magnetic field. The U.S. aeromagnetic data are updated and available from the United States Geological Survey (USGS) Geophysical Products. NCEI continues to archive and serve data for main field modeling. All marine and airborne trackline surveys can be accessed via our Map Viewer.
