Polar ionospheric currents and high temporal resolution geomagnetic field models
Clemens Kloss, Christopher C. Finlay, Karl M. Laundal +1
Estimating high resolution models of the Earth's core magnetic field and its time variation in the polar regions requires that one can adequately account for magnetic signals produ…
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…
Applications for CryoSat2 satellite magnetic data in studies of Earth's core field variations
Magnus Danel Hammer, Christopher C. Finlay, Nils Olsen
We use 20 years of magnetic field measurements from the Oersted, CHAMP and Swarm satellite missions, supplemented by calibrated platform magnetometer data from the CryoSat2 satelli…
Co-estimating geomagnetic field and calibration parameters: modeling Earth's magnetic field with platform magnetometer data
Clemens Kloss, Christopher C. Finlay, Nils Olsen
Models of the geomagnetic field rely on magnetic data of high spatial and temporal resolution. The magnetic data from low-Earth orbit satellites of dedicated magnetic survey missio…
The CHAOS-7 geomagnetic field model and observed changes in the South Atlantic Anomaly
Christopher C. Finlay, Clemens Kloss, Nils Olsen +4
We present the CHAOS-7 model of the time-dependent near-Earth geomagnetic field between 1999 and 2020 based on magnetic field observations collected by the low-Earth orbit satellit…
Sunlight effects on the 3D polar current system determined from low Earth orbit measurements
Karl M. Laundal, Christopher C. Finlay, Nils Olsen
Interaction between the solar wind and the Earth's magnetosphere is associated with large-scale currents in the ionosphere at polar latitudes that flow along magnetic field lines (…
