The total columnar electron content of the equatorial ionosphere

Journal of Atmospheric and Terrestrial Physics, 1967
Abstract The Faraday rotation technique is applied to study the features of the variations of the total columnar electron content at an equatorial station. Absence of a noon bite-out and the occurrence of a maximum near 1430 L.M.T. are some of the regular characteristics of the diurnal variation.

Lunar variation of total electron content at Lunping

Journal of Atmospheric and Terrestrial Physics, 1978
Abstract The lunar daily variations of the ionospheric total electron content observed at Lunping, which lies close to the crest zone of the so called equatorial anomaly, were computed by the Chapman-Miller method. The lunar semi-diurnal variation of TEC was found to be explainable by the additional fountain effect caused by the lunar semi-diurnal ...

Measurements of total electron content at Huancayo, Peru

Planetary and Space Science, 1970
Abstract Measurements of total electron content of the ionosphere above Huancayo, Peru by observation of Faraday fading of satellite signals during January through March 1967 are reported. The data are examined to study principally the diurnal variation of total electron content and of equivalent slab thickness as well as the latitudinal variation of

Correlation analysis of vertical total electron content

Acta Geophysica, 2010
It is necessary to model and analyze the ionospheric effects due to a direct relationship between Global Positioning System (GPS) applications and changes in the ionosphere. In order to monitor these changes, the ionosphere can be represented by the vertical total electron content (VTEC) which can be used to analyze ionospheric conditions from a ...

Modelling of Ionospheric Irregularities and Total Electron Content.

1983
Abstract : F-region irregularities near the equator are viewed from the concept of the temporal structure of UHF scintillations and the electron content depletions associated with VHF, UHF and GHz scintillations. Near the equatorial anomaly crest, the solar cycle effect on GHz scintillation and the depolarization of VHF satellite signals are probed ...
