A preliminary validation of the technique developed using the NeQuick ionospheric model and the «effective ionization
parameter» Az, based on vertical total electron content data ingestion, was carried out in a previous study. The
current study was performed to extend the analyzed conditions and confirm the results. The method to validate this
technique is based on a comparison between hourly F2 peak values measured with Vertical Incidence (VI) soundings
and those calculated with the new technique. Data corresponding to different hours and seasons (equinox, summer
solstice, and winter solstice) during the period 2000-2003 (high and medium solar activity conditions) were compared
for all available ionosonde stations. The results show a good agreement between foF2 and hmF2 values obtained with
the new technique and measurements from vertical incidence soundings during quiet and storms conditions.
