Interplanetary Electric Fields for Extreme Magnetic Storms

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Using a list of sudden‐commencement storms, the ring‐current index, and 1‐h near‐Earth solar‐wind measurements from solar cycles 20–25, we develop extreme‐value statistical models relating storm intensity D=max{−Dst} $D=\max \left\{-Dst\right\}$ to the storm main‐phase maximum duskward interplanetary electric field E $E$.

The British Geological Survey's New Geomagnetic Data Web Service

open access: yesData Science Journal, 2013
Increasing demand within the geomagnetism community for high quality real-time or near-real-time observatory data means there is a requirement for data producers to have a robust and scalable data processing infrastructure capable of delivering ...

Teoloyucan geomagnetic observatory operation over a quality management system ISO 9001:2015 [PDF]

open access: yesGeoscientific Instrumentation, Methods and Data Systems
Geomagnetic observatories are essential for the study of the Earth's magnetic phenomena; they allow the precise and continuous measurement of the geomagnetic field.

A new geomagnetic observatory network?

open access: yesEos, Transactions American Geophysical Union, 1993
Input and comments are solicited for a study of the network of geomagnetic observatories. Although there are some 200 geomagnetic observatories around the world recording the intensity and direction of the geomagnetic field, they were established over the last 2 centuries without any overall plan and do not satisfy many of today's scientific and ...

Anomalous changes of vertical geomagnetic field in Kamchatka

open access: yesE3S Web of Conferences, 2016
Secular variations of the vertical geomagnetic field at Paratunka (Kamchatka), Kakioka (Honshu), Mamambetsu (Hokkaido) and Patrony (Irkutsk) are considered from 1968 to 2014.

Geomagnetic Secular Variation at the Indian Observatories.

open access: yesJournal of geomagnetism and geoelectricity, 1997
Annual mean values of geomagnetic field components D, H and Z for all days and quiet days at six observatories are analysed to investigate the secular variations and geomagnetic jerks in the Indian region. Secular trends show a region of demarkation between equatorial and low latitude stations.

An Investigation into Techniques for Isolating Noise in Observatory Data

open access: yesData Science Journal, 2011
In this study, using one-minute definitive data published by a number of INTERMAGNET observatories, we apply a number of time- and frequency-domain techniques to characterise the global, natural geomagnetic signal and isolate the artificial noise at an ...

Availability and Access to Data from Kakioka Magnetic Observatory, Japan

open access: yesData Science Journal, 2013
The Japan Meteorological Agency (JMA) is operating four geomagnetic observatories in Japan. Kakioka Magnetic Observatory (KMO), commissioned in 1913, is the oldest. The hourly records at KMO cover over almost 100 years.

Geomagnetic Surveys by the Geospatial Information Authority of Japan and the Contribution of the Kakioka Magnetic Observatory

open access: yesData Science Journal, 2013
The Geospatial Information Authority of Japan (GSI) has been conducting geomagnetic surveys in Japan since 1949 to clarify the geographical distribution of direction, intensity of the geomagnetic field, and their secular variations.
