Anomalous Secular Variation of Geomagnetic Total Intensity In Chugoku District, Japan [PDF]
In 1971 Geomagnetic surveys in the Chugoku district have been carried out by using a portable proton precession magnetometer. The ordinary method of epoch reduction to eliminate non-local changes in the geomagnetic field has been slightly modified by ...

The Earth's magnetic field varies over a wide range of characteristic times, say, from years to centuries, and more. In order to detect some nonlinear features of the geomagnetic field evolution we first apply a nonlinear spectral technique, i.e ...

Abstract The substorm current wedge constitutes the backbone of the substorm current system. Its field‐aligned current components include an upward current in the premidnight sector and a downward current in the midnight‐morning sector, which connect the auroral ionosphere to the magnetotail.

Abstract The geomagnetic storm on 1 June 2025 generated pronounced large‐scale traveling ionospheric disturbances (LSTIDs) over China, captured by dense GNSS networks. It has been unclear whether network real‐time kinematic (NRTK) positioning, which relies on spatial interpolation from multiple reference stations, remains effective under such extreme ...

The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

Report on the magnetic survey in Slovakia for the 2014.5 epoch
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.

Simple additional constraints on regional models of the geomagnetic secular variation field
Lecter section of Physics of the Earth and Planetary Interiors 97 (1996)Standard ways of building regional models of the geomagnetic field fail when one wishes to model secular variation (SV).

Bottom-up control of geomagnetic secular variation by the Earth's inner core
Temporal changes in the Earth’s magnetic field, known as geomagnetic secular variation, occur most prominently at low latitudes in the Atlantic hemisphere1, 2 (that is, from −90 degrees east to 90 degrees east), whereas in the Pacific hemisphere there is
