Simulation study of the influence of the ionospheric layer height in the thin layer ionospheric model
(Springer, 2011-04)
This work aims to contribute to the understanding of the influence of the ionospheric layer height (ILH) on the thin layer ionospheric model (TLIM) used to retrieve ionospheric information from the GNSS observations. ...
CIGALA: Challenging the solar maximum in Brazil with PolaRxS
(2011-12-01)
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 ...

Extended ionospheric amplitude scintillation model for GPS receivers
(Amer Geophysical Union, 2014-05-01)
Ionospheric scintillation is a phenomenon that occurs after sunset, especially in the low-latitude region, affecting radio signals that propagate through the ionosphere. Depending on geophysical conditions, ionospheric ...
Brazilian active GNSS networks as systems for monitoring the ionosphere
(2017-07-01)
This research shows the viability of using Global Navigation Satellite System (GNSS) stations from Brazilian active networks in monitoring the ionosphere. Various indexes of ionospheric irregularities and scintillation of ...
Unexpected connections between the stratosphere and ionosphere
(American Geophysical Union, 2010-05)
The coupling of the ionosphere to processes from below remains an elusive and difficult problem, as rapidly changing external drivers from above mask variations related to lower atmospheric sources. Here we use superposition ...
Modeling ionospheric super‐fountain effect based on the coupled TIMEGCM‐SAMI3
(American Geophysical Union, 2013-04-02)
Recently, efforts have been undertaken to develop a coupled thermosphere‐ionosphere‐plasmasphere model based on two well‐established models, namely, the Thermosphere‐Ionosphere‐Mesosphere General Circulation Model (TIMEGCM) ...
Ionospheric disturbances before and after the january 14, 2018 earthquake in Peru
(Academy of Sciences of the Czech Republic, 2019)
An earthquake of Mw 7.1 occurred on January 14, 2018 in the southern coast of Peru. In this study, public available Global Ionospheric Maps (GIMs) provided by the Center for Orbit Determination in Europe (CODE) were used ...
A case study for the IONEX CODE-database processing tool software: Ionospheric anomalies before the Mω 8.2 earthquake in Mexico on September 7, 2017
(Science and Information Organization, 2018)
A software tool was developed in the Imaging Processing Research laboratory (INTI-Lab) that automatically downloads several IONEX files around a specific user input date and also performs statistical calculations to look ...
