The lithospheric contribution to the Earth's magnetic field is concealed in magnetic field data
that have now been measured over several decades from ground to satellite altitudes. The …

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 …

We use more than 2 years of magnetic data from the Swarm mission, and monthly means
from 160 ground observatories as available in March 2016, to update the CHAOS time …

We present CHAOS-4, a new version in the CHAOS model series, which aims to describe
the Earth's magnetic field with high spatial and temporal resolution. Terms up to spherical …

Geomagnetic jerks are abrupt changes in the second time derivative—the secular
acceleration—of Earth's magnetic field that punctuate ground observatory records. As their …

While high‐degree models of the Earth's gravity potential have been inferred from
measurements for more than a decade, corresponding geomagnetic models are difficult to …

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 …

We present DTU's candidate field models for IGRF-12 and the parent field model from which
they were derived, CHAOS-5. Ten months of magnetic field observations from ESA's Swarm …

The secular variation of the core field is generally characterized by smooth variations,
sometimes interrupted by abrupt changes, named geomagnetic jerks. The origin of these …

The geomagnetic secular acceleration (SA), defined as the second‐order time derivative of
the Earth's core magnetic field, is investigated using data from the CHAMP satellite. We …
