GRACE magnetometer data now available to support Swarm Sciences

24 May 2022

We are pleased to announce the new release of magnetic field data recorded by Fluxgate magnetometers operating on-board the two GRACE satellites.

The newly released data cover the period January 2008 until October 2017 and will be particularly useful to complement Swarm data in characterising Earth's magnetic field variations and the near Earth's space environment.

More information on the calibration technique applied to this dataset are available in the Olsen, N. Magnetometer data from the GRACE satellite duo. Earth Planets Space 73, 62 (2021) https://doi.org/10.1186/s40623-021-01373-9

The data, produced as daily CDF files, can be found on the Swarm FTP server in the "Multimission/GRACE" folder.
