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 …

The magnetic field inside the Earth's fluid and electrically conducting outer core cannot be
directly probed. The root-mean-squared (rms) intensity for the resolved part of the radial …

Modern observations of the geomagnetic field reveal fluctuations,, with a dominant period of
about 60 years. These fluctuations are probably a result of waves in the liquid core, although …

The magnetic field of the Earth is by far the best documented magnetic field of all known
planets. Considerable progress has been made in our understanding of its characteristics …

A large part of the Earth's magnetic field is generated by fluid motion in the molten outer
core. As a result of continuous satellite measurements since 1999, the core magnetic field …

We present core flows constructed from high resolution secular variation (SV) models for the
epochs 2001, 2002.5 and 2004, assuming that these flows are quasi-geostrophic in the core …

The magnetic fields of planets and stars are thought to play an important role in the fluid
motions responsible for their field generation, as magnetic energy is ultimately derived from …

Data assimilation in geomagnetism designates the set of inverse methods for geomagnetic
data analysis which rely on an underlying prognostic numerical model of core dynamics …

Ground observatory and satellite-based determinations of temporal variations in the
geomagnetic field probe a decadal to annual timescale range where Earth's core slow …
