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 ...
Low latitude storm time ionospheric electrodynamics
(Elsevier, 2002-04-30)
The response of the low latitude ionosphere to high latitude convection has long been the subject of considerable interest. Radar, ionosonde, magnetometer, and satellite measurements have been extensively used for studying ...
Relative effects of electric field and neutral wind on positive ionospheric storms
(SpringerOpen, 2009-05-14)
The paper studies the relative importance of penetrating eastward electric field (PEEF) and direct effects of equatorward neutral wind in leading to positive ionospheric storms at low-mid latitudes using observations and ...
Observations of the April 2002 geomagnetic storm by the global network of incoherent scatter radars
(European Geosciences Union (EGU), 2005-01)
This paper describes the ionospheric response to a geomagnetic storm beginning on 17 April 2002. We present the measurements of ionospheric parameters in the F-region obtained by the network of eight incoherent scatter ...
Comparative study of the equatorial ionosphere over Jicamarca during recent two solar minima
(American Geophysical Union, 2012-01-21)
It is a critical issue that whether or not the extremely deep solar minimum of solar cycle 23/24 brought serious influences on the Earth's space environment. In this study, we collected and manually scaled the ionograms ...
Equatorial spread-F initiation: Post-sunset vortex, thermospheric winds, gravity waves
(Elsevier, 2007-12)
We present experimental evidence and modeling results which indicate that eastward thermospheric wind is the primary controlling factor of equatorial spread-F initiation in the post-sunset ionosphere. Eastward wind-driven ...
Collisional shear instability in the equatorial F region ionosphere
(American Geophysical Union, 2004-11-03)
A collisional shear instability in a magnetized plasma is described and evaluated. The instability is related to electrostatic Kelvin Helmholtz but operates in inhomogeneous plasmas in the collisional regime. Boundary value ...
Comparison of topside equatorial parameters derived from DMSP, Jicamarca, and Another Model of the Ionosphere (SAMI2)
(American Geophysical Union, 2005-01-19)
Comparison is made of topside equatorial parameters obtained from DMSP satellites with those measured from Jicamarca radar and those calculated from Another Model of the Ionosphere (SAMI2). To determine acceptable limits ...
Equatorial ionospheric zonal drift model and vertical drift statistics from UHF scintillation measurements in South America
(European Geosciences Union, 2004-09)
UHF scintillation measurements of zonal ionospheric drifts have been conducted at Ancon, Peru since 1994 using antennas spaced in the magnetic east-west direction to cross-correlate geo-synchronous satellite signals. An ...
Multistation digisonde observations of equatorial spread F in South America
(European Geosciences Union (EGU), 2004-09)
Directional ionogram and F-region drift observations were conducted at seven digisonde stations in South America during the COPEX campaign from October to December 2002. Five stations in Brazil, one in Argentina, and one ...
