The physical measurement of the main variables involved in the different layers of the atmosphere in the face of eminent climate change can provide records that contribute to the modeling, forecasting, prediction and simulation of the climate. In particular, the purpose of this work focuses on the modeling of the temperature profile at different stages of flight, emphasizing the Tropopause. The profile was obtained by several thermometers inside and outside the module "Experimental Module for the Iterative Design for Satellite Subsystems Ver.1" and recorded on the on board computer. This is a collaboration project between the CDA-IPN and ICAT-UNAM. The module was launched with NASA's help on the FY19-FTS mission within the 11MCF#697N platform in September 2019 from Fort Sumner, New Mexico-USA of the Columbia Scientific Balloon Facility Program. The profiles are compared with similar suborbital flights with high altitude platforms and international atmospheric standards for the study and predictions between the troposphere and the stratosphere.
