                         low-latitude ionosphere over Brazil was monitored in two 
                         dimensions by using 2011 data from the ground-based global 
                         navigation satellite system (GNSS) receiver network operated by 
                         the Brazilian Institute for Geography and Statistics. It was 
                         possible to monitor the spatial and temporal variations in TEC 
                         over Brazil continuously during both day and night with a temporal 
                         interval of 10 min and a spatial resolution of about 400 km. The 
                         daytime equatorial ionization anomaly (EIA) and post-sunset plasma 
                         enhancement (PS-EIA) were monitored over an area corresponding to 
                         a longitudinal extension of 4000 km in South America. Considerable 
                         day-to-day variation was observed in EIA and PS-EIA. A large 
                         latitudinal and longitudinal gradient of TEC indicated a 
                         significant ionospheric range error in application of the GNSS 
                         positioning system. Large-scale plasma bubbles after sunset were 
                         also mapped over a wide range. Depletions with longitudinally 
                         separated by more than 800 km were observed. They were extended by 
                         more than 2000 km along the magnetic field lines and drifted 
                         eastward. It is expected that 2-dimensional TEC mapping can serve 
                         as a useful tool for diagnosing ionospheric weather, such as 
                         temporal and spatial variation in the equatorial plasma trough and 
                         crest, and particularly for monitoring the dynamics of plasma 
                         bubbles.",
