Small-scale structure of the geodynamo inferred from Oersted and Magsat satellite data
The ‘geodynamo’ in the Earth's liquid outer core produces a magnetic field that dominates the large and medium length scales of the magnetic field observed at the Earth's surface. Here we use dataExpand

CHAOS—a model of the Earth's magnetic field derived from CHAMP, Ørsted, and SAC‐C magnetic satellite data
SUMMARY We have derived a model of the near-Earth magnetic field (up to spherical harmonic degree n = 50 for the static field, and up to n = 18 for the first time derivative) using more than 6.5 yrExpand

Rapidly changing flows in the Earth's core
Variations in the Earth’s magnetic field over a span of a few months can be resolved despite the potential filtering effects of the electrically conducting mantle, and are indicative of rapid flow inExpand

Crustal magnetic field of Mars
[1] The equivalent source dipole technique is used to model the three components of the Martian lithospheric magnetic field. We use magnetic field measurements made on board the Mars Global SurveyorExpand

Investigation of a secular variation impulse using satellite data: The 2003 geomagnetic jerk
Abstract Observatory monthly means provide an excellent opportunity to study the temporal changes of the magnetic field at a given location. Unfortunately, the uneven distribution of the presentExpand

CHAOS-2—a geomagnetic field model derived from one decade of continuous satellite data
SUMMARY We have derived a model of the near-Earth's magnetic field using more than 10 yr of high-precision geomagnetic measurements from the three satellites Orsted, CHAMP and SAC-C. This model isExpand

Geomagnetic Jerks: Rapid Core Field Variations and Core Dynamics
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 events, observed andExpand

GRIMM: the GFZ Reference Internal Magnetic Model based on vector satellite and observatory data
SUMMARY In this paper the new GFZ Reference Internal Magnetic Model (GRIMM) is presented. The model has been derived from nearly 6 yr of CHAMP satellite data and 5 yr of observatory hourly means. AtExpand
