Diagnostics of equatorial and low latitude ionosphere by TEC mapping over Brazil
(Elsevier B.V., 2014)
Diagnostics of equatorial and low latitude ionosphere by TEC mapping over Brazil
(Elsevier B.V., 2014)
Unusual early morning development of the equatorial anomaly in the Brazilian sector during the Halloween magnetic storm
(Amer Geophysical Union, 2014)
A real‐time forecast service for the ionospheric equatorial zonal electric field
(American Geophysical Union, 2012-09-18)
The zonal electric field is the primary driver of two important features of the equatorial ionosphere: (1)The Equatorial Ionization Anomaly (EIA), and (2) plasma density irregularities, also known as spread‐F. During ...
The effects of the pre-reversal drift, the EIA asymmetry, and magnetic activity on the equatorial spread F during solar maximum
(European Geosciences Union, 2005-03-30)
We use a digisonde at Jicamarca and a chain of GPS receivers on the west side of South America to investigate the effects of the pre-reversal enhancement (PRE) in ExB drift, the asymmetry (Ia) of equatorial ionization ...
Study of the F3 and StF4 Layers at Tucumán Near the Southern Crest of the Equatorial Ionization Anomaly in Western South America
(Blackwell Publishing, 2018-03)
The present investigation reports for the first time seasonal and solar activity variations of F3 and StF4 layers at the low-latitude station of Tucumán (26.9°S, 65.4°W; dip latitude 13.9°S), Argentina, by considering ...
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 ...
Equatorial F-layer heights, evening prereversal electric field, and night E-layer density in the American sector: IRI validation with observations
(Elsevier, 2004)
The equatorial F-layer height variations resulting from the variabilities in the zonal electric fields and winds and associated variability in ionospheric dynamo strength are important factors in determining the distribution ...
A simulation study on the impact of altitudinal dependent vertical plasma drift on the equatorial ionosphere in the evening
(American Geophysical Union, 2015-02-28)
We carry out a simulation study on the impact of altitudinal dependent plasma drift on the equatorial ionosphere in the evening, under geomagnetically quiet conditions. Our study used the vertical plasma drift velocity ...
Effects of disturbed electric fields in the low‐latitude and equatorial ionosphere during the 2015 St. Patrick's Day storm
(American Geophysical Union, 2016-09-02)
The 2015 St. Patrick's Day geomagnetic storm with SYM‐H value of −233 nT is an extreme space weather event in the current 24th solar cycle. In this work, we investigated the main mechanisms of the profound ionospheric ...
