Solar flare effect on the geomagnetic field and ionosphere
(Elsevier, 2009-08)
This paper studies the ionospheric and geomagnetic response to an X6.2 solar flare recorded at 14:30 UT on December 13, 2001, in quiet geomagnetic conditions which allow the variations in the geomagnetic field and ionosphere ...
Electric field and magnetometer observations of the equatorial electrojet: An IEEY program
(Instituto Geofísico del Perú, Radio Observatorio de Jicamarca, 1994)
As part of the IEEY program, a chain of magnetometers was deployed along the Peruvian sector crossing the equatorial electrojet. Simultaneous vertical drift measurements were made using Jicamarca's normal I.S. F-region ...

Dating of Holocene fluvial deposits in the southern Sierras Pampeanas (Argentina) by matching paleomagnetic secular variation to a geomagnetic field model
(Pergamon-Elsevier Science Ltd, 2021-03-02)
A 2-m long Holocene sedimentary sequence collected from a fluvial system located in the eastern piedmont of Sierra de Las Quijadas (San Luis, Argentina) was dated by comparing its paleomagnetic secular variation (PSV) ...
Can a nightside geomagnetic Delta H observed at the equator manifest a penetration electric field?
(American Geophysical Union, 2013-02-12)
A prompt penetration electric field (PPEF) usually manifests itself in the form of an equatorial ionospheric electric field being in correlation with a solar wind electric field. Due to the strong Cowling conductivity, a ...

The first case study of a thunderstorm in South Africa based on dual- Doppler radar observations
(1992-12-01)
On 27 March 1991, an isolated thunderstorm passed between the two CSIR Doppler radars, spaced about 45km apart. Both radars simultaneously recorded Doppler data of the storm, and a detailed case study during an 11-min ...
