                         Santa Maria in April 2017, is analyzed in this work. Medium values 
                         of the F-region critical frequency (foF2), peak height (hmF2), and 
                         F2-layer thickness parameter (Bo) scaled from ionograms are

                         Ionospheric (IRI-2016) model predictions, for the same geophysical 
                         conditions and location. We have considered the DPS4D observations 
                         taken in the five magnetically quiet days of October 2017, 
                         January, April and July 2018 as representatives of the Southern 
                         Hemisphere spring, summer, autumn, and winter, respectively. The 
                         results are presented and discussed taken into account the
