Abstract
This study deals with Peak of electron density in F2-layer sensibility scale during quiet time on solar minimum. Peaks of electron density in F2-layer (NmF2) values at the quietest days are compared to those carried out from the two nearest days (previous and following of quietest day). The study uses International Reference Ionosphere (IRI) for ionosphere modeling. The located station is Ouagadougou, in West Africa. Solar minimum of phase 22 is considered in this study. Using three core principles of ionosphere modeling under IRI running conditions, the study enables to carry out Peak of electron density in F2-layer values during the quietest days of the characteristic months for the four different seasons. These parameters are compared to those of the previous and the following of the quietest days (the day before and following each quietest selected day) at the same hour. The knowledge of NmF2 values at the quietest days and at the two nearest days enables to calculate the relative error that can be made on this parameter. This calculation highlights insignificant relative errors. This means that NmF2 values at the two nearest days of each quietest day on solar minimum can be used for simulating the quietest days’ behavior. NmF2 values obtained by running IRI model have good correlation with those carried out by Thermosphere-Ionosphere-Electrodynamics-General Circulation Model (TIEGCM).

Summary
This layer moves like a plasma and so, is electrically neutral. Ionization of particles in ionosphere layer due to solar radiations creates electrons and ions in the layer. Ionosphere composition in particles enables to determine the critical frequency of radio waves frequency of transmitters. The present study is focused on the calculation of relative error on Peak of electron density in F2-layer values at the limits of the quietest days for different seasons during solar minimum, compared to those of the quietest days. The study is based on quiet time variation of solar cycle 22 at Ouagadougou station and uses International Reference Ionosphere (IRI) model for ionosphere investigation.
