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 Stolle, Claudia GFZ German Research Centre for Geosciences, Potsdam, Germany claudia.stolle@gfz-potsdam.de pointOfContact Michaelis, Ingo GFZ German Research Centre for Geosciences, Potsdam, Germany ingo.michaelis@gfz-potsdam.de pointOfContact Earth Observation Satellites > NASA Earth System Science Pathfinder > GRACE-FO Platform Magnetometers Satellite-based magnetometers Earth's magnetic field Geomagnetism Earth Remote Sensing Instruments > Passive Remote Sensing > Magnetic Field/Electric Field Instruments > MAGNETOMETERS Earth Remote Sensing Instruments > Passive Remote Sensing > Magnetic Field/Electric Field Instruments > MTQ Solar/Space Observing Instruments > Magnetic Field/Electric Field Instruments > FLUXGATE MAGNETOMETERS GCMD Instruments publication EARTH SCIENCE > SOLID EARTH > GEOMAGNETISM > MAGNETIC FIELD EARTH SCIENCE > SUN-EARTH INTERACTIONS > IONOSPHERE/MAGNETOSPHERE DYNAMICS NASA/GCMD Earth Science Keywords publication CC BY 4.0 CC BY 4.0 10.1186/s40623-021-01364-w DOI IsSupplementTo 10.1029/2010JA015326 DOI Cites 10.1186/s40623-020-01252-9 DOI Cites 10.5880/GFZ.2.3.2022.001 DOI Cites https://cdf.gsfc.nasa.gov/ URL Cites https://isdc.gfz-potsdam.de/grace-fo-isdc URL References eng geoscientificInformation 1Hz -180 180 -89 89 2018-06-01 2020-10-31T23:59:59 http://doi.org/10.5880/GFZ.2.3.2021.002 WWW:LINK-1.0-http--link Data Access - DOI Data Access - DOI information
