             abstract = "In the present study, we document daytime total electron content 
                         (TEC) disturbances associated with medium-scale traveling 
                         ionospheric disturbances (MSTIDs), on few chosen geomagnetically 
                         quiet days over Southern Hemisphere of Brazilian longitude sector. 
                         These disturbances are derived from TEC data obtained using Global 
                         Navigation Satellite System (GNSS) receiver networks. From the 
                         keograms and cross-correlation maps, the TEC disturbances are 
                         identified as the MSTIDs that are propagating 
                         equatorward-eastward, having most of their average wavelengths 
                         longer in latitude than in longitude direction. These are the 
                         important outcomes of the present study which suggest that the 
                         daytime MSTIDs over Southern Hemisphere are similar to their 
                         counterparts in the Northern Hemisphere. Another important outcome 
                         is that the occurrence characteristics of these MSTIDs and that of 
                         atmospheric gravity wave (AGW) activities in the thermosphere are 
                         found to be similar on day-to-day basis. This suggests a possible 
                         connection between them, confirming the widely accepted AGW 
                         forcing mechanism for the generation of these daytime MSTIDs. The 
                         source of this AGW is investigated using the Geostationary 
                         Operational Environmental Satellite system (GOES) and 
                         Constellation Observing System for Meteorology, Ionosphere, and 
                         Climate satellite data. Finally, we provided evidences that AGWs 
                         are generated by convection activities from the tropospheric 
                         region.",
