All updates

The purpose of SuperMAG is to help scientists, teachers, students and the general public have easy access to measurements of the Earth's magnetic field.

SuperMAG is funded by NSF, NASA and ESA.

SuperMAG is a worldwide collection of geomagnetic ground station data and provides innovative products and services. All raw data is sourced from institutes around the world operating magnetometers and SuperMAG thanks these institutes and their funding bodies. SuperMAG data are not equivalent to the original data.
