This data set contains the calibrated DC magnetic field from the GEOS-2 S-331 fluxgate magnetometer in VDH Coordinate System in nT. The time resolution is 22.016s.

Users of these data are encouraged to acknowledge ESA/ESTEC (European Space Agency / European Space Research and Technology Center), DSRI (Danish Space Research Institute), CNES (Centre National d'Etudes Spatiales) for their support to the SCM GEOS team, NASA/GSFC (National Aeronautics and Space Administration / Goddard Space Flight Center) and CNR (Consiglio Nazionale delle Ricerche) for their support to the MAG GEOS team, and the CDPP (Centre des Données de la Physique des Plasmas) for the distribution of the GEOS data, in all publications. If PI/coI are not part of the publication list, then we suggest to add Specifically, we acknowledge Roger Gendrin and Patrick Robert for use of SCM data from the GEOS mission.

Magnetic field components

Magnetic field components given in VDH Coordinate System.

VDH frame (Vertical Dusk Horizontal system)
The V-axis is the outwards local vertical, to the point of observation.The H-axis is parallel to the horizontal local plane, positive to the North.The V-H plane is a geographic meridian plane. The D-axis is azimuthal, eastwards.
