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…
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…
Recent north magnetic pole acceleration towards Siberia caused by flux lobe elongation
Philip W. Livermore, Christopher C. Finlay, Matthew Bayliff
The wandering of Earth's north magnetic pole, the location where the magnetic field points vertically downwards, has long been a topic of scientific fascination. Since the first in…
Time-dependent low latitude core flow and geomagnetic field acceleration pulses
Clemens Kloss, Christopher Finlay
We present a new model of time-dependent flow at low latitudes in the Earth's core between 2000 and 2018, derived from magnetic field measurements made on board the {\it Swarm} and…
