A new source of the midlatitude ionospheric peak density structure revealed by a new Ionosphere‐Plasmasphere model
(American Geophysical Union, 2016-02-02)
The newly developed Ionosphere‐Plasmasphere (IP) model has revealed neutral winds as a primary source of the “third‐peak” density structure in the daytime global ionosphere that has been observed by the low‐latitude ...
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, ...
The accuracy potential of Galileo E5/E1 pseudoranges for surveying and mapping
(2011-12-01)
In the paper we discuss the potential of the new Galileo signals for pseudorange based surveying and mapping in open areas under optimal reception conditions (open sky scenarios) and suboptimal ones (multipath created by ...
Unexpected connections between the stratosphere and ionosphere
(American Geophysical Union, 2010-05)
The coupling of the ionosphere to processes from below remains an elusive and difficult problem, as rapidly changing external drivers from above mask variations related to lower atmospheric sources. Here we use superposition ...
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 ...
Photoelectron transport and energy balance in the low-latitude ionosphere
(Cornell University, 2012)
Theoretical studies of ionospheric structure and dynamics require knowledge of the underlying thermal structure of the ionosphere since it affects the chemical reaction rates, recombination rates, and pressure gradients. ...
Combined radar observations of equatorial electrojet irregularities at Jicamarca
(European Geosciences Union (EGU), 2007-03-08)
Daytime equatorial electrojet plasma irregularities were investigated using five distinct radar diagnostics at Jicamarca including range-time-intensity (RTI) mapping, Faraday rotation, radar imaging, oblique scattering, ...
Linear Vary-Chap Topside Electron Density Model with Topside Sounder and Radio-Occultation Data
(2019-03-01)
The Linear Vary-Chap function has received increased attention in describing the topside ionosphere due to its good performance for predicting and extrapolating radio-occultation (RO) electron density ionospheric profiles. ...
Ingestion of FORMOSAT-3/COSMIC GPS data into La Plata Ionospheric Model: A preliminary assessment
(Elsevier, 2017-08)
La Plata Ionospheric Model (LPIM; Brunini et al., 2011) has been upgraded to a new stage enabling the ingestion of sTEC values retrieved from GPS receivers on board the FORMOSAT-3 Constellation Observing System for ...
Overview of a New Reconstruction Method to Map the Ionosphere at the Brazilian Region
(Inst Navigation, 2018-01-01)
Three-dimensional ionospheric reconstruction at the Brazilian area has been a continuous challenge due to the high ionospheric variability and lack of data in the region. Many efforts have been conducted to overcome these ...
