Dynamical and magnetic field time constants for Titan's ionosphere: Empirical estimates and comparisons with Venus
(American Geophysical Union, 2010-10)
Plasma in Titan´s ionosphere flows in response to forcing from thermal pressure gradients, magnetic forces, gravity, and ion-neutral collisions. This paper takes an empirical approach to the ionospheric dynamics by using ...
Post-Storm Middle and Low-Latitude Ionospheric Electric Fields Effects
(Springer, 2016-12-05)
The Earth’s upper atmosphere and ionosphere undergoes large and complex perturbations during and after geomagnetic storms. Thermospheric winds driven by enhanced energy and momentum due to geomagnetic activity generate ...
Stormtime dynamics of the global thermosphere and equatorial ionosphere
(European Geosciences Union, 2009-05-05)
During magnetic storms the development of equatorial plasma bubbles (EPBs) and distributions of thermospheric densities are strongly influenced by the histories of imposed magnetospheric electric (εM) fields. Periods of ...
Storm-time equatorial thermospheric dynamics and electrodynamics
(Utah State University, 2020)
It presents the first comprehensive study of the equatorial thermospheric dynamics and ionospheric electrodynamics over Peru following enhanced energy depositions into the high-latitude ionosphere during geomagnetic storms. ...
Towards forecasting and mitigating ionospheric scintillation effects on GNSS
(Ieee, 2007-01-01)
The effect of the ionosphere on the signals of Global Navigation Satellite Systems (GNSS), such as the Global Positionig System (GPS) and the proposed European Galileo, is dependent on the ionospheric electron density, ...
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 ...
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 ...
Quiet-time variations of F2-layer parameters at Jicamarca and comparison with IRI-2001 during solar minimum
(Elsevier, 2008)
We analyze Jicamarca ionograms to study the quiet-condition variations in the peak electron density (NmF2), its height (hmF2), and F2-layer thickness parameter (B0) of the equatorial F2 layer during solar minimum. The ...
Comparison between bottomside ionospheric profile parameters retrieved from FORMOSAT3 measurements and ground-based observations collected at Jicamarca
(Elsevier, 2011-03-11)
This study presents the results of a comparison of three ionospheric profile parameters, B0, NmF2, and hmF2, derived from measured ionograms and the FORMOSAT3 radio occultation measurements collected over Jicamarca during ...
Solar-wind magnetosphere effects in the middle and low latitude ionosphere
(2004-01-01)
Ionospheric electric fields play fundamental roles in the dynamics of the Earth's ionosphere and thermosphere. Enhanced geomagnetic activity has long been known to cause large ionospheric electric field and current ...
