Modeling electron density in ionosphere D region by IRI-2016 during 22 maximum solar cycle phase at Ouagadougou station

Abstract

Ionosphere region is the site of radio waves reflection for communication. Ionosphere behaves as an obstacle for
radio waves emitted by stations. This part of atmosphere lays from 50km up to 2000km. Many models have been
developed for ionosphere layer investigation to give a good knowledge of the composition in particles (electrons,
ions, atoms and molecules) of this layer. Particles density in this layer gives it the reflectivity to radio waves
emitted from stations. Some models are based on mathematical approaches, while others use data provided by
stations. This work deals with peak of electron density in D layer of ionosphere region by use of the 2016 -version
of International Reference Ionosphere (IRI) model. The study uses quiet days of 22 solar cycle phase under low
latitudes, at Ouagadougou station, located in West Africa. Seasonal and time profiles of electron density in D layer
of ionosphere are extracted by running the model. The study also interprets the disappearance of D layer at
nighttime by introducing the concepts of ionosphere nighttime and ionosphere daytime in D layer.
