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.

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.

A Compensation Method for the Geomagnetic Measurement Error of an Underwater Ship-Borne Magnetometer Based on Constrained Total Least Squares

Sensors
When magnetic matching aided navigation is applied to an underwater vehicle, the magnetometer must be installed inside the vehicle, considering the navigation safety and concealment of the underwater vehicle.

A Prospection‐Led Archaeological Investigation of a Picenian and Roman Necropolis in Corinaldo (Marche, Italy)

Archaeological Prospection, EarlyView.
ABSTRACT This paper presents the results of an integrated archaeological and geophysical investigation conducted between 2018 and 2024 at the newly discovered Picenian and Roman necropolis of Contrada Nevola (Corinaldo, Marche, Central Italy), identified in the framework of development‐led archaeology. The research strategy combined aerial photography,

A multisource geomagnetic field model incorporating ocean circulation-induced magnetic field

Earth and Planetary Physics
The movement of global ocean circulation in the Earth’s main magnetic field generates a measurable induced magnetic field (about 2 nT at geomagnetic satellite altitudes).

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.

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 model of the geomagnetic non-dipole field.

Journal of geomagnetism and geoelectricity, 1983
Yukutake's model separates the geomagnetic field into drifting and standing parts, not only fits well to the observed field for the past several hundred years, but also emphasizig the regularities of the westward drift of the geomagnetic non-dipole field. However, there are still some problems to be reinvestigated:a) In Yukutake's model the geomagnetic
