             abstract = "Ground-based network of GNSS receivers have been used to monitor 
                         Equatorial Plasma Bubbles (EPBs) by mapping the Total Electron 
                         Content (TEC map). Large coverage of the TEC map allowed us to 
                         monitor several EPBs simultaneously and get characteristics of the 
                         dynamics, extension and longitudinal distributions of the EPBs 
                         from the onset time until their disappearance. These 
                         characteristics were obtained by using TEC map analysis and 
                         keogram technique by using the data obtained during the period 
                         between November/2012 and January/2016. The zonal drift velocities 
                         of the EPBs showed a clear latitudinal gradient varying from 123 
                         m/s at the equator to 65 m/s for 35S of latitude. Consequently, 
                         observed EPBs are inclined against the geomagnetic field lines. 
                         Both zonal drift velocity and the inclination of the EPBs were 
                         compared with the thermospheric neutral wind, which showed a good 
                         agreement. Moreover, large coverage of TEC maps permit to study 
                         periodic EPBs with a wide longitudinal distance. This averaged 
                         values observed for the inter-bubbles distances also presented a 
                         clear latitudinal gradient varying from 920 km at the equator to 
                         640 km at 30S. On several occasions, the distances reached more 
                         than 2000 km. Inter-bubbles distances greater than 1000 km have 
                         not been reported in literature. Numerical model calculations, 
                         using different latitudinal gradients in zonal wind, showed a good 
                         agreement with the latitudinal gradient in the EPBs zonal drift 
                         observed by TEC map. Comparison of the observational results with 
                         the theoretical model calculations confirms that the EPB 
                         inclination against the geomagnetic field lines and the 
                         latitudinal gradient of inter-bubbles distances were originated 
                         due to a latitudinal gradient in the.",
