Co-estimation of core and lithospheric magnetic fields by a maximum entropy method
Mikkel Otzen, Christopher C. Finlay, Clemens Kloss
Satellite observations of the geomagnetic field contain signals generated in Earth's interior by electrical currents in the core and by magnetized rocks in the lithosphere. At shor…
Quasi-geostrophic convection-driven dynamos in a thick spherical shell
Olivier Barrois, Thomas Gastine, Christopher C. Finlay
We present dynamos computed using a hybrid QG-3D numerical scheme in a thick spherical shell geometry. Our model is based on a quasi-geostrophic convection code extended with a 3D…
Assimilation of ground and satellite magnetic measurements: inference of core surface magnetic and velocity field changes
Olivier Barrois, Magnus D. Hammer, Christopher C. Finlay +2
We jointly invert for magnetic and velocity fields at the core surface over the period 1997-2017, directly using ground-based observatory time series and measurements from the CHAM…
Comparison of Quasi-Geostrophic, Hybrid and 3D models of planetary core convection
Olivier Barrois, Thomas Gastine, Christopher C. Finlay
We present investigations of rapidly-rotating convection in a thick spherical shell geometry relevant to planetary cores, comparing results from Quasi-Geostrophic, 3D and hybrid QG…
