Australian Cosmic Ray Modulation Research [PDF]

, 2000
Australian research into variations of the cosmic ray flux arriving at the Earth has played a pivotal role for more than 50 years. The work has been largely led by the groups from the University of Tasmania and the Australian Antarctic Division and has ...

IGRF commercialization defeated, planetary studies probed by IAGA

Eos, Transactions American Geophysical Union, 1991
Sessions of the International Association of Geomagnetism and Aeronomy (IAGA) at the XX International Union of Geodesy and Geophysics meeting in Vienna, Austria (August 11–24), lasted for nearly the full 2 weeks of the conference. Once again, the program offered a vast array of scientific topics ranging from the outer limits of the heliosphere to ...

Rotation in the Southeastern Caribbean Arc (Grenadines) Accommodated by Back‐Arc Basin Inversion

Tectonics, Volume 45, Issue 4, April 2026.
Abstract The Caribbean tectonic plate is typically modeled as a rigid plate moving along discrete plate boundaries. Isolated exposures on islands have long shown that above the Lesser Antilles subduction zone, the plate experienced contractional, strike‐slip, and extensional deformation, but the importance of this deformation remained long unknown ...

Comparison of IGRF models with North American magnetic data

Journal of geomagnetism and geoelectricity, 1982
Comparisons of proposed and adopted geomagnetic reference field models are made against North American test data for the period 1965 to 1985. These test data (X, Y, Z, and F) include Canadian map and aeromagnetic data and USGS land-based data. Model values are also tested against predicted component values for 1982 and 1984 derived from 27 magnetic ...

MISTA candidate magnetic field models for IGRF-14 derived from MSS-1, Swarm and observatory data

Earth, Planets and Space
The International Geomagnetic Reference Field (IGRF) is a spherical harmonic model representing the large-scale Earth’s main magnetic field and its secular variation (SV).

Global Mapping of Near-Earth Magnetic Fields Measured by KITSAT-1 and KITSAT-2 [PDF]

Journal of Astronomy and Space Sciences, 1994
The magnetic field measurements from the KitSat-1 and KitSat-2 were tested by comparing with the IGRF model. The magnetic data have been collected by a three-axis fluxgate magnetometer on each satellite at an altitude of 1,325km and 820km, respectively ...

New Phoenix Magnetic Anomaly Data Confirms Global Nature of Jurassic Quiet Zone and Provides Insight Into Early Pacific Spreading

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We demonstrate the presence of the oldest identifiable marine magnetic anomalies in the Phoenix lineations of the western Pacific based on careful assessment of new data. Recently acquired sea surface magnetic anomalies and multichannel seismic profiles confirm magnetic signals recorded within the Middle‐Jurassic to Early Cretaceous basement ...

Cosmic ray cutoff prediction using magnetic field from global magnetosphere MHD simulations [PDF]

Annales Geophysicae, 2005
Relativistic particles entering the Earth's magnetosphere, i.e. cosmic rays and solar energetic particles, are of prime space weather interest because they can affect satellite operations, communications, and the safety of astronauts and airline ...

Numerical analysis of lognormal diffusions on the sphere

, 2016
Numerical solutions of stationary diffusion equations on the unit sphere with isotropic lognormal diffusion coefficients are considered. H\"older regularity in $L^p$ sense for isotropic Gaussian random fields is obtained and related to the regularity of ...
