             abstract = "The equatorial ionosphric plasma distribution, dynamics and 
                         structuring are known to undergo significant variations with solar 
                         activity. The specific parameters of the present interest concern 
                         the F layer height, vertical plasma drift and plasma 
                         bubbles/spread F irregularities that are controlled by the sunset 
                         electrodynamic processes. The evening prereversal electric field 
                         enhancement/vertical plasma drift is responsible for a resurgent 
                         plasma fountain and the associated ionization anomaly and plasma 
                         bubble irregularity developments, all of which present significant 
                         dependence on solar activity, their intensities generally 
                         increasing with the solar activity. The extensive data sets 
                         available from the Brazilian network of Digisonds and GPS 
                         receivers are being analyzed to investigate the nature of the 
                         solar activity dependence with respect to the different parameters 
                         of interest. This paper will present an evaluation of the solar 
                         activity dependence in the different parameters as obtained from 
                         observational data in comparison with that predicted in the IRI 
                         scheme.",
