Abstract
This work deals with electron surface density time variation in ionosphere region. The study uses international reference ionosphere (IRI) model for investigation. Total Electron Content (TEC) parameter is carried out at different levels in the F2-layer of ionosphere. The study takes place at Ouagadougou station (12,4°N and 358,5°E), in West Africa. Quiet time periods of solar cycle 22 are considered. This study considers only the maximum and minimum phases of solar cycle 22. The five quietest days of the characteristic months in each season are used in the study. Seasonal time profiles of ionosphere parameters highlight relation between Total Electron Content (TEC) and Height of F2-layer (hmF2) in ionosphere region. The results found in this study correlate closely with parameters behavior previously found in other works.
Highlights
The Sun emits radiations through all the space
The panels show that at minimum solar cycle phase, Total Electron Content (TEC) time profile decreases at nighttime and increases during daytime
In this study, electron bulk surface density behavior is highlighted at different positions of F2-layer on a station located at low latitudes
Summary
The Sun emits radiations through all the space. These radiations hit the particles in the atmosphere and cause their ionization. From 50km up to almost 800km in the atmosphere, the density of particles is important (Bauer et al, 1962, 1964; Van Zandt et al, 1960, 1964). This part of the atmosphere is the ionosphere layer. It’s the site where reflect radio waves for telecommunication In this region, the major constituents in particles are N2, O2 and O (Rishbett et al, 1969). The present study uses international reference ionosphere (IRI) model for ionosphere investigation. IRI is a semi-empirical model using data recorded on different stations. The parameters are obtained for the different seasons of 1985 and 1990 at Ouagadougou station located in West Africa, near the equator
