Geomagnetic main field modeling with DMSP [PDF]

Journal of Geophysical Research: Space Physics, 2014
AbstractThe Defense Meteorological Satellite Program (DMSP) launches and maintains a network of satellites to monitor the meteorological, oceanographic, and solar‐terrestrial physics environments. In the past decade, geomagnetic field modelers have focused much attention on magnetic measurements from missions such as CHAMP, Ørsted, and SAC‐C.

Recovering external contribution from the monthly mean series of a given geomagnetic observatory

Annals of Geophysics, 2016
The differences between monthly mean values of the observed geomagnetic field and monthly values predicted by different models of the internal geomagnetic field (named “model biases”) for the time period 2000-2015 at several geomagnetic observatories are

Development of a Systematic Model for Study on the Phenomena of Ionospheric and Geomagnetic Variations [PDF]

Journal of Astronomy and Space Sciences, 1999
Solar activities ejecting high energy particles influence satellites and satellite communications as well as perturb geomagnetic fields. To understand space environments near the Earth being influenced by the Sun, we must study about the magnetosphere ...

Radiation Resilient Synthetic Antiferromagnets‐Based Neuromorphic Device for Sea Surface Temperature Reconstruction

Advanced Science, EarlyView.
By leveraging strong antiferromagnetic coupling, radiation‐tolerant synthetic antiferromagnetic synaptic devices are developed. Their intrinsic nonlinearity emulates neuronal activation, while linear and symmetric conductance modulation mimics synaptic plasticity.

Models and predictions of Earth’s magnetic field based on geomagnetic observatory data

Earth, Planets and Space
Observations of the geomagnetic field taken at Earth’s surface are processed to construct a set of continuous models of the geomagnetic field and its secular variation from 1956 to 2033.

Shannon information of the geomagnetic field for the past 7000 years [PDF]

Nonlinear Processes in Geophysics, 2010
The present behaviour of the geomagnetic field as expressed by the International Geomagnetic Reference Field (IGRF) deserves special attention when compared with that shown over the past few thousands of years by two paleomagnetic/archeomagnetic models ...

The CHAOS-4 geomagnetic field model [PDF]

Geophysical Journal International, 2014
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 degree of at least n = 85 for the lithospheric field, and up to n = 16 for the time-varying core field are robustly determined.More than 14 yr of data from the satellites Ørsted,

A global climatological model of extreme geomagnetic field fluctuations [PDF]

Journal of Space Weather and Space Climate, 2020
This paper presents a multi-parameter global statistical model of extreme horizontal geomagnetic field fluctuations (dBH/dt), which are a useful input to models assessing the risk of geomagnetically induced currents in ground infrastructure. Generalised Pareto (GP) distributions were fitted to 1-min measurements of |dBH/dt| from 125 magnetometers (with

Remote Roca: Integrating Data From Archaeological Survey, Remote Sensing and Geophysics in the Hinterland at the Long‐Lasting Mediterranean Site of Rocavecchia (Apulia, Italy)

Archaeological Prospection, EarlyView.
ABSTRACT This study presents a multi‐method non‐invasive investigation of an approximately 4‐ha area associated with the long‐occupied coastal settlement of Rocavecchia (Apulia, southern Italy), situated between the prehistoric fortified peninsula and the Hellenistic‐Messapian walls.
