Turbulent motions of liquid metal in Earth's outer core generate the geomagnetic field.
Magnetic field observations from low-Earth-orbit satellites, together with advanced numerical …

Evidence of fast variations in the Earth's core field are seen both in magnetic observatory
and satellite records. We present here how they have been identified at the Earth's surface …

We present an attempt to reach realistic turbulent regime in direct numerical simulations of
the geodynamo. We rely on a sequence of three convection-driven simulations in a rapidly …

The strength of the geomagnetic field has decreased rapidly over the past two centuries,
coinciding with an increasing field asymmetry due to the growth of the South Atlantic …

Swarm is the first European Space Agency (ESA) constellation mission for Earth
Observation. Three identical Swarm satellites were launched into near-polar orbits on 22 …

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 situ …

Our understanding of the geodynamo has recently progressed thanks to geomagnetic data
of improved quality, and analyses resting on numerical simulations of increasing realism …

We make use of recent geodynamo simulations to propose a reduced stochastic model of
the dynamics at the surface of Earth's core. On decadal and longer periods, this model …

Abstract The European Space Agency's three-satellite constellation Swarm, launched in
November 2013, has provided unprecedented monitoring of Earth's magnetic field via a …

Geomagnetic observations from satellites have highlighted interannual variations in the rate
of change of the magnetic field originating from Earth's core. Downward continued to the …
