A Major Update to the PyIRI Model
Space Weather, Volume 24, Issue 6, June 2026.Abstract This paper presents a major update to the PyIRI model, a fully vectorized Python implementation of the International Reference Ionosphere (IRI). The update reformulates the IRI core coefficients using spherical harmonics in Quasi‐Dipole (QD) latitude and Magnetic Local Time coordinates, replacing the legacy geographic‐coordinate‐based basis ...

Report on the magnetic survey in Slovakia for the 2014.5 epoch
Contributions to Geophysics and Geodesy, 2016 The models of the distribution of the elements of the geomagnetic field must be updated regularly. For this purpose geomagnetic measurements have to be carried out repeatedly at geomagnetic observatories as well as at temporary observation points.

Iridium Communications Satellite Constellation Data for Study of Earth's Magnetic Field
Geochemistry, Geophysics, Geosystems, 2021 Characterization of Earth's magnetic field is key to understanding dynamics of the core. We assess whether Iridium Communications magnetometer data can be used for this purpose since.

Advancing Heliophysics and Space Weather Modeling Through Open Science
Space Weather, Volume 24, Issue 6, June 2026.Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

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 ...

The working of the IGRF 2000 Task Force [PDF]
Earth, Planets and Space, 2014 At its meeting in July 1999, the IAGA Working Group for Analysis of the Global and Regional Geomagnetic Field and Secular Variation (WG V-8) felt unable to decide on a main-field model to use for IGRF 2000. It therefore set up a small Task Force with the remit to produce a model by the end of the year. This paper is the Chairman’s report of the working

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract This study highlights the need to re‐evaluate energy transfer in the upper thermosphere at high latitudes through analysis of 9‐year measurements of neutral wind (u) from a Fabry‐Perot interferometer and ion velocity (v) from a Dynasonde in Tromsø, Norway.

Eos, Transactions American Geophysical Union, 1969 A Fortran II Computer program has been developed by the U.S. Coast and Geodetic Survey to compute the International Geomagnetic Reference Field (IGRF) for any geographic position. To facilitate the portrayal and comparison of magnetic anomalies, the IGRF is used as a common datum for removal of regional gradients from magnetic survey measurements. This
