             abstract = "Gravity waves observed in the troposphere play an important role 
                         in the transport of energy and momentum between lower and middle 
                         atmosphere, changing the thermal structure and general circulation 
                         in these regions. However, gravity waves generated by tropical 
                         convection are generally not well simulated in global circulation 
                         models, remaining as an area of science that deserves research and 
                         investment. The use of models capable of explicitly solving 
                         moisture transport and heating associated with convective clouds 
                         is relatively recent, as well as applications of data assimilation 
                         on this scale. On the other hand, only a few observation systems 
                         have a high vertical resolution and sample the upper troposphere 
                         and lower stratosphere, making difficult to obtain a detailed 
                         description of the spectrum of gravity waves generated by deep 
                         convection. Observations derived from the radio occultation (RO) 
                         of the Global positioning system (GPS) signals are able to assist 
                         in this task and have been explored to study atmospheric waves and 
                         coupling processes, especially in regions where ground-based 
                         temperature profiles are not provided. The high vertical 
                         resolution of temperature profiles derived from GPS RO technique 
                         and its global coverage, allowed to study the mesoscale 
                         temperature fluctuations caused by atmospheric waves in the 
                         stratosphere as well as analyze internal parameters of gravity 
                         waves. The present study aims to review previus works on the use 
                         of GPS RO profiles to explore gravity waves characteristics. Some 
                         results of the gravity waves activity in South America will be
