Secular variation signals in magnetic field gradient tensor elements derived from satellite-based geomagnetic virtual observatories

Magnus Danel Hammer, Christopher C. Finlay, Nils Olsen

We present local time-series of the magnetic field gradient tensor elements at satellite altitude derived using a Geomagnetic Virtual Observatory (GVO) approach. Gradient element t…
