Electric fields in the equatorial ionosphere derived from CHAMP satellite magnetic field measurements
(Elsevier, 2009-03-09)
The day-time eastward equatorial electric field (EEF) in the E-region plays an important role in equatorial ionospheric dynamics. It is responsible for driving the equatorial electrojet (EEJ) current system, equatorial ...
A case study of ionospheric storm effects during long‐lasting southward IMF Bz‐driven geomagnetic storm
(American Geophysical Union, 2014-08-27)
Multiple instrumental observations including GPS total electron content (TEC), foF2 and hmF2 from ionosondes, vertical ion drift measurements from Communication/Navigation Outage Forecasting System, magnetometer data, and ...
Longitudinal variations of positive dayside ionospheric storms related to recurrent geomagnetic storms
(American Geophysical Union, 2013-10-31)
We have performed an analysis of case events and statistics of positive ionospheric storms in the dayside region of the equatorial ionization anomaly during recurrent geomagnetic storms (RGSs), which dominate in geomagnetic ...
Titan ionospheric conductivities from Cassini measurements
(Elsevier, 2009-12)
(approximately the location of the exobase) to approximately 1000 km where electrical currents perpendicular to the magnetic field may become important. In this region the ionosphere is highly conductive with peak Pedersen ...
An empirical approach to modeling ion production rates in Titan's ionosphere II: Ion production rates on the nightside
(American Geophysical Union, 2015-02)
onization of neutrals by precipitating electrons and ions is the main source of Titan's nightside ionosphere. This paper has two goals: (1) characterization of the role of electron impact ionization on the nightside ...
Radar measurements of gravity waves in the ionosphere
(1974)
Some characteristic parameters of gravity waves at D and E region heights such as amplitude, frequency spectrum and spatial properties can and have been measured by means of VHF radars. One of the techniques makes use of ...
Low‐ and mid‐latitude ionospheric electric fields during the January 1984 GISMOS Campaign
(American Geophysical Union, 1990-03)
An alternative approach for estimating E region density profiles using radio occultation total electron content (ROTEC) measurements is presented. In this approach, the F region contribution to the measured ROTEC is removed ...
Improved electron density measurements at Jicamarca
(American Geophysical Union, 2007-11-27)
Taking into account the effects of electron Coulomb collisions, incoherent scatter (IS) radar cross sections for probing angles close to perpendicular to the magnetic field have been calculated and used to correct backscattered ...
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 ...
Dynamic variability in F-region ionospheric composition at auroral arc boundaries
(2010)
The work presents a data-model synthesis examining
the response of the auroral F-region ion temperature,
composition, and density to short time scale (<1 min)
electric field disturbances associated with auroral arcs. ...
