GRACE-FO calibrated and characterized magnetometer data

Description: GRACE-FO carries a magnetometer as part of its attitude orbit control system (AOCS). The magnetometer does not belong to the scientific payload of the mission. However, after postprocessing of the data, information on the geomagnetic field and on electric currents in near Earth space are derived. Each GRACE-FO satellite (GF1 and GF2) carries two fluxgate magnetometers (FGM), an active one, FGM A, and a redundant one, FGM B. So far, the redundant magnetometers were not switched and are not included in the data set. The provided data consists of raw magnetic field data as provided by L1b (RAW), Magnetic field data aligned, calibrated and corrected (ACAL_CORR), CHAOS7 magnetic model predictions for core, crustal and large-scale magnetospheric field (CHAOS7), Magnetic coordinates (APEX) and Radial and field-aligned currents derived from magnetic data in ACAL_CORR (FAC). The data are provided in NASA CDF format (https://cdf.gsfc.nasa.gov/). Data categories RAW: Raw magnetic field data as provided by L1b ACAL_CORR: Magnetic field data, aligned, calibrated and corrected CHAOS7: CHAOS7 magnetic model predictions for core, crustal and large-scale magnetospheric field APEX: Magnetic coordinates (Emmert et al, 2010) FAC: Radial and field-aligned currents derived from magnetic data in ACAL_CORR
