Multifractal characteristics of geomagnetic field fluctuations for the northern and southern hemispheres at swarm altitude
(MDPI, 2021)
This paper explores the spatial variations of the statistical scaling features of low to high latitude geomagnetic field fluctuations at Swarm altitude. The data for this study comes from the vector field magnetometer ...
Methods for the measurement of vertical ionospheric motions near the magnetic equator by incoherent scattering
(American Geophysical Union, 1969-03-01)
Methods are discussed for the measurement of motions of the ionosphere by means of Doppler shifts of incoherent scatter frequency spectra. It is found that velocities can be measured with an accuracy of better than a few ...
Archeointensity in Northeast Brazil over the past five centuries
(ELSEVIER SCIENCE BV, 2010)
This study presents the first archeointensity results from Northeast Brazil obtained from 14 groups of architectural brick fragments sampled in the city of Salvador, Bahia State (13 degrees S, 38.5 degrees W) and dated ...
Ionospheric Conductance Spatial Distribution During Geomagnetic Field Reversals
(American Geophysical Union, 2018-03)
The conductivity of the ionosphere is extremely important in geophysical processes and plays acritical role in magnetosphere-ionosphere-thermosphere coupling. Understanding its nature is essential tounderstand the physics ...
Peculiar features of the low‐latitude and midlatitude ionospheric response to the St. Patrick's Day geomagnetic storm of 17 March 2015
(American Geophysical Union, 2016-07-25)
The current study aims at investigating and identifying the ionospheric effects of the geomagnetic storm that occurred during 17–19 March 2015. Incidentally, with SYM‐H hitting a minimum of −232 nT, this was the strongest ...
The effect of the geomagnetic field on cosmic ray energy estimates and large scale anisotropy searches on data from the Pierre Auger Observatory
(Institute of Physics - IOPBristol, 2011-11)
We present a comprehensive study of the influence of the geomagnetic field on the energy estimation of extensive air showers with a zenith angle smaller than 60°, detected at the Pierre Auger Observatory. The geomagnetic ...
RINEX_HO: second- and third-order ionospheric corrections for RINEX observation files
(Springer Heidelberg, 2011-07-01)
When GNSS receivers capable of collecting dual-frequency data are available, it is possible to eliminate the first-order ionospheric effect in the data processing through the ionosphere-free linear combination. However, ...

The role of the zonal ExB plasma drift in the low-latitude ionosphere at high solar activity near equinox from a new three-dimensional theoretical model
(European Geosciences Union (EGU), 2006-10-20)
A new three-dimensional, time-dependent theoretical model of the Earth's low and middle latitude ionosphere and plasmasphere has been developed, to take into account the effects of the zonal E×B plasma drift on the electron ...
