Galactic Cosmic Rays Production at the Equator and Magnetic Poles at the Minimum and Maximum Solar Activity

Nakolemda Roger, Sawadogo Gédéon, Konaté Moustapha & Nanéma Emmanuel · Current Journal of Applied Science and Technology · 2022

Cosmic rays is composed of charged particles, created and possibly accelerated in the remains of supernovas. The measurement of cosmic ray fluxes allows to put constraints on their sources and their transport, but also to consider the problem of these radiations in the terrestria...

Seasonal Variability of foE and Nocturnal Winter Anomaly in E-layer during Solar Cycles 21 and 22 at the Ouagadougou Station

Sawadogo Gédéon, Nakolemda Roger, Konaté Moustapha & Nanéma Emmanuel · Physical Science International Journal · 2022

This paper aims to study the variability of foE during two solar cycles 21 (SC21) and 22 (SC22) at Ouagadougou station (lat = 12.4°N, long = 358.5°E, local time (LT) = universal time (UT)), to give visibility on the behavior of foE in this station. We used International Reference...

Variability of f_o E in Relation to the Solar Indices (R_z and F_(10.7) ) at the Equatorial Ionosphere (Ouagadougou Station)

Sawadogo Gédéon, Konaté Moustapha, Nakolemda Roger & Nanéma Emmanuel · Asian Journal of Physical and Chemical Sciences · 2022

The correlation coefficients between the critical frequency of the ionosphere E-layer ( foE )and the solar radio flux have not been formally evaluated at the Ouagadougou station. The purpose of this paper is to conduct a study on the variability of the critical frequency of ionos...
