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…
Direct Sequential Simulation for spherical linear inverse problems
Mikkel Otzen, Christopher C. Finlay, Thomas Mejer Hansen
We present a method for obtaining efficient probabilistic solutions to geostatistical and linear inverse problems in spherical geometry. Our Spherical Direct Sequential Simulation…
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…
Time-scale dependence of solar wind-based regression models of ionospheric electrodynamics
K. M. Laundal, J. P. Reistad, S. M. Hatch +6
The solar wind influence on geospace can be described as the sum of a directly driven component, or dayside reconnection, and an unloading component, associated with the release of…
