dc.description.abstract	In this paper, the ways of improving the equatorial F2 layer peak heights estimated from M(3000)F2 ionosonde data measured using the Ionospheric Prediction Service (IPS-42) sounder at Ouagadougou, Burkina Faso (geog lat +12.4°N, geog long +1.5°W, magnetic dip +5.9°N) during high solar activity year (1991) was investigated. For this purpose, the observed height of maximum electron density of F2 region (h_mF2_obs), deduced using an algorithm from scaled virtual heights of quiet day ionograms; and the predicted h_mF2 values, which is given by the IRI 2007 model (h_mF2_IRI2007) have been compared with the ionosonde measured M(3000)F2 estimation of the h_mF2 values (h_mF2_est), respectively. A strong correlation with its coefficients R² for all the seasons ranging 0.562 - 0.857 for h_mF2_obs values, and ranging 0.876 - 0.968 for the h_mF2_IRI2007values was observed in the linear regressions of h_mF2_obs and h_mF2_IRI2007 with M(3000)F2 inverse. During the nighttime, estimated h_mF2 (h_mF2_est) was found to be positively correlated with the h_mF2_obsvalues by the post-sunset peak representation, which is not represented by the h_mF2_IRI2007values. Also, the validity of the h_mF2_estvalues has been investigated by finding the percentage deviations when compared with the h_mF2_obs and h_mF2_IRI2007.	en_US
