Thermosphere-Ionosphere response at middle and high latitudes during perturbed conditions: A case study
(Elsevier, 2008-12)
Neutral gas composition and ionospheric measurements taken by the Dynamic Explorer 2 satellite at F2-region heights (280–300 km) during an intense geomagnetic storm (peak Dst=−187 nT) were used to analyze the role of some ...
IonMAP: Sistema de assimilação de dados para o imageamento tridimensional da ionosfera no Brasil
(Universidade Estadual Paulista (Unesp), 2019-01-25)
A considerável variação espaço-temporal da densidade eletrônica na atmosfera superior terrestre torna a ionosfera uma região de difícil modelagem. Parte dos modelos que utilizam as observáveis do Sistema Global de Navegação ...
Test and Evaluation of Ionospheric Monitoring Performance for Dongying Shengli Airport东营胜利机场电离层监测性能的测试与评估
(Beihang UniversityCN, 2020)
Storm time dependence of equatorial disturbance dynamo zonal electric fields
(American Geophysical Union, 1997-11-01)
We use Jicamarca radar observations of F region vertical plasma drifts and auroral electrojet indices during 1968–1988 to study the characteristics and temporal evolution of equatorial disturbance dynamo zonal electric ...
Predictions of HF system performance for propagation through disturbed ionospheres measured using low‐Earth‐orbit satellite radio beacon tomography
(American Geophysical Union, 2014-07)
The CERTO radio beacon on the C/NOFS satellite sends VHF/UHF radio signals at 150 and 400 MHz to provide measurements of integrated electron density or Total Electron Content (TEC) by an east‐west chain of ground receivers ...
Estimating the daytime Equatorial Ionization Anomaly strength from electric field proxies
(American Geophysical Union, 2008-09-10)
The Equatorial Ionization Anomaly (EIA) is a significant feature of the low‐latitude ionosphere. During daytime, the eastward electric field drives a vertical plasma fountain at the magnetic equator creating the EIA. Since ...
