We are pleased to announce the new release of magnetic field data recorded by Fluxgate magnetometers operating on-board the two Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) satellites.

The newly released data are produced as daily CDF files and cover the period June 2018 until March 2022. The dataset can be found in the Swarm FTP server, in the "Multimission/GRACE-FO/" folder.

More information on the calibration technique applied to this dataset are available in Stolle, C., Michaelis, I., Xiong, C. et al. Observing Earth's magnetic environment with the GRACE-FO mission. Earth Planets Space 73, 51 (2021). https://doi.org/10.1186/s40623-021-01364-w
