%X Atmospheric gravity waves (AGWs) are an essential mechanism in the transport of energy and momentum flux from the low to the upper atmosphere. In the last decades satellite observations have become an important part in the analysis of AGWs due to their global and frequent coverage. Global Positioning Satellite (GPS) radio occultation (RO) is a well-established technique for obtaining AGWs information. Temperature profiles are derived with high vertical resolution and provide a global coverage under any weather conditions, offering the possibility of global and regional monitoring of the vertical temperature structure and atmospheric wave parameters. In this study, temperature profiles from RO measurements over South American sector were employed to study the atmospheric coupling of the troposphere, stratosphere, and mesosphere through the dynamic process of AGWs in the range of 20 km and 50 km in altitude. The results of the specific potential energy (Ep), vertical wavenumber, the horizontal and vertical wavelengths, and the vertical flux of horizontal momentum (MF) are calculated. Their temporal (day-today) and spatial variations over South America will be presented.
