                         affected by the ionospheric conditions, which are controlled by 
                         solar phenomena associated with radiation variations and solar 
                         wind disturbances. These phenomena can generate ionospheric 
                         large-scale plasma redistribution and irregularities with scale 
                         sizes varying from centimeters to hundred kilometers. These 
                         ionospheric irregularities can produce rapid fluctuations in the 
                         amplitude and phase of global navigation satellite system (GNSS) 
                         signals, degrading the accuracy of GNSS measurements. Here we give 
                         a short review of the ionospheric variations associated with solar 
                         phenomena, and the actual state of art in the investigations of 
                         long-term (seasonal and solar cycle scales) TEC variations and 
                         climatology of scintillations, with focus on the southern American 
                         sector. It also presented a new TEC calibration procedure when
