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. ...
The equatorial E-region and its plasma instabilities: a tutorial
(European Geosciences Union, 2009-04-02)
In this short tutorial we first briefly review the basic physics of the E-region of the equatorial ionosphere, with emphasis on the strong electrojet current system that drives plasma instabilities and generates strong ...
Simultaneous 6300 Å airglow and radar observations of ionospheric irregularities and dynamics at the geomagnetic equator
(European Geosciences Union (EGU), 2018-03-22)
In March 2014 an all-sky imager (ASI) was installed at the Jicamarca Radio Observatory (11.95°S, 76.87°W; 0.3°S MLAT). We present results of equatorial spread F (ESF) characteristics observed at Jicamarca and at low ...
The wavelet method as an alternative for reducing ionospheric effects from single-frequency GPS receivers
(Springer, 2007-12-01)
The ionospheric effect is one of the major errors in GPS data processing over long baselines. As a dispersive medium, it is possible to compute its influence on the GPS signal with the ionosphere-free linear combination ...
Statistical analysis of radar observed F region irregularities from three longitudinal sectors
(European Geosciences Union, 2013-12)
Equatorial Spread F (ESF) is a manifestation of ionospheric interchange instabilities in the nighttime equatorial F region. These instabilities generate plasma density irregularities with scale sizes ranging from centimetres ...
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 ...
Imaging radar observations and nonlocal theory of large-scale plasma waves in the equatorial electrojet
(European Geosciences Union (EGU), 2002)
Large-scale (λ∼1 km) waves in the daytime and nighttime equatorial electrojet are studied using coherent scatter radar data from Jicamarca. Images of plasma irregularities within the main beam of the radar are formed using ...
Statistical characteristics of low latitude ionospheric field-aligned irregularities obtained with the Piura VHF radar
(European Geosciences Union, 2002-03)
We present a summary of the statistical characteristics of echoes from ionospheric (E- and F-region) field- aligned irregularities obtained with the Piura VHF radar. This radar is located at ∼7.0° dip latitude, just outside ...
High altitude large-scale plasma waves in the equatorial electrojet at twilight
(European Geosciences Union (EGU), 2004-12-24)
Jicamarca radar observations of a new class of large-scale plasma waves in the equatorial electrojet (EEJ) are presented and characterized. The study is based on long-term (204 days), single-baseline interferometry ...
