Sporadic E layer development and disruption at low latitudes by prompt penetration electric fields during magnetic storms
(American Geophysical Union, 2013-04-11)
An investigation of low‐latitude sporadic E layers during magnetic storms shows that the formation and disruption of these layers are strongly controlled by the magnetospheric electric fields that penetrate to equatorial ...
On ionic contributions to Pedersen conductance
(Blackwell Publishing Ltd, 2018-12)
Ionospheric conductivity is a key parameter to understand the upper atmosphere electrodynamics, magnetosphere-ionosphere-thermosphere coupling and several geophysical processes. In the case of Pedersen conductivity, ions ...
The Ionospheric Spectral Imager (ISI):A digital spectrometric Riometer.
(Universidad de Concepción.Facultad de Ciencias Físicas y Matemáticas, 2023)
Radiometric systems’ theory and application are fundamental to human progress, holding significance in telecommunications, electronics, medical devices, and beyond. In our investigation, they play a vital role in studying ...
Análisis de los flujos extremos de electrones energéticos en el cinturón de radiación exterior y en la anomalía magnética del Atlántico SurAnalysis of extreme energetic electron fluxes in the outer radiation belt and South Atlantic magnetic anomaly
(Centro Argentino de Meteorólogos, 2021-07)
Los cinturones de radiación de van Allen son regiones en el entorno espacial terrestre que presentan iones y electrones energéticos atrapados por el campo geomagnético. El incremento del flujo para estas partículas energéticas ...
CIGALA: Challenging the Solar Maximum in Brazil with PolaRxS
(Inst Navigation, 2011-01-01)
The upcoming solar maximum, which is expected to reach its peak around May 2013, occurs at a time when our reliance on high-precision GNSS has reached unprecedented proportions. The perturbations of the ionosphere caused ...
Assessing the GNSS scintillation climate over Brazil under increasing solar activity
(2013-12-01)
We study ionospheric scintillation on GNSS signals at equatorial latitudes to draw a climatological picture of the low latitude ionosphere in the Brazilian sector during the ascending phase of the upcoming 2013 solar ...
Gateways and climate: The Drake Passage opening
(Istituto Nazionale di Oceanografia e di Geofisica, 2010-06)
The Oligocene opening of the Drake Passage between the southern tip of South America and the Antarctic Peninsula, and the subsequent evolution of the Scotia plate, have definitively separated Antarctica from the other ...
