                         (GNSS) receivers over South American continent, TECMAP, have been 
                         operationally produced by Instituto Nacional de Pesquisas 
                         Espaciaiss Space Weather Study and Monitoring Program (Estudo e 
                         Monitoramento Brasileiro de Clima Especial) since 2013. In order 
                         to cover the whole continent, four GNSS receiver networks, (Rede

                         TECMAPs with a time resolution of 10 min are produced in 12 h time 
                         delay. Spatial resolution of the map is rather low, varying 
                         between 50 and 500 km depending on the density of the observation 
                         points. Large day-to-day variabilities of the equatorial 
                         ionization anomaly have been observed. Spatial gradient of TEC 
                         from the anomaly trough (total electron content unit, 1 TECU = 
                         1016 el m2 (TECU) <10) to the crest region (TECU > 80) causes a 
                         large ionospheric range delay in the GNSS positioning system. 
                         Ionospheric plasma bubbles, their seeding and development, could 
                         be monitored. This plasma density (spatial and temporal) 
                         variability causes not only the GNSS-based positioning error but 
                         also radio wave scintillations. Monitoring of these phenomena by 
                         TEC mapping becomes an important issue for space weather concern
