(Universidade Federal do Pampa, 2017)
Abnormal evening vertical plasma drift and effects on ESF and EIA over Brazil-South Atlantic sector during the 30 October 2003 superstorm
(2008-07-01)
Equatorial F region vertical plasma drifts, spread F and anomaly responses, in the south American longitude sector during the superstorm of 30 October 2003, are analyzed using data from an array of instruments consisting ...

Effect of Prompt Particle Events on OLCI Ocean Color Imagery in the South Atlantic Anomaly: Detection and Removal
(Institute of Electrical and Electronics Engineers, 2018-10)
It has been found that cosmic rays and massive charged particles trapped in the magnetosphere or arriving from the sun might produce spike noise over the dark offset signal coming from charge-coupled devices (CCDs) on optic ...
Electron precipitation associated with geomagnetic activity: Balloon observation of X ray flux in South Atlantic anomaly
(Amer Geophysical UnionWashington, 1997)
Moho depth and equivalent elastic thickness of the lithosphere over the Vema Channel: A new evidence of an aborted ridge
(2018-03-01)
We investigate the Vema Channel in terms of spatial variations of the elastic thickness (Te) in the frame of the thin plate flexure model using the convolutive method. The modeling of the Moho in terms of the thin plate ...
Longitudinal ionospheric effects in the South Atlantic evening sector during solar maximum
(American Geophysical Union, 2002-07-10)
Large-scale horizontal gradients in ion density and vertical drift observed by the Atmospheric Explorer E satellite in the South Atlantic region (latitudes 10S–20S, longitudes 50W–10E) during the June solstice at solar ...
Latitudinal variation rate of geomagnetic cutoff rigidity in the active Chilean convergent margin
(European Geosciences Union, 2018)
Abstract. We present a different view of secular variation
of the Earth’s magnetic field, through the variations in the
threshold rigidity known as the variation rate of geomagnetic
cutoff rigidity (VRc). As the geomagnetic ...
