                         observed by GPS receivers over two equatorial stations in South 
                         America with large difference in magnetic declination angle, 
                         S{\~a}o Lu{\'{\i}}s (2.33° S, 315.8ºE, declination: -19o) in 
                         Brazil and Arequipa (16.5°S, 288.5ºE, declination: 0.5o) in Peru. 
                         The TEC variations for three solar activity levels (high, moderate 
                         and low) have been analyzed. The TEC values recorded over S{\~a}o 
                         Lu{\'{\i}}s are larger than those over Arequipa. The rate of 
                         increase of the TEC with intensification of the solar activity is 
                         also different at the two sites, independent of the season and 
                         local time. One of the main aims of the present work is to 
                         investigate the longitudinal differences in the TEC values 
                         associated with the large variations in the magnetic declination 
                         angle using the Sheffield University Plasmasphere Ionosphere Model 
                         (SUPIM). The zonal electric field effects on the TEC magnitudes 
                         over the two South America stations will be discussed.",
