This GAP note represents two updates on studies related to atmospheric depth prole.The original studies were presented in previous Auger Collaboration Meetings but they havenot been documented inside the Auger Collaboration. Despite the fact that today the dataanalysis in our experiment is made with GDAS, these models are very useful to cross checkingand simulation studies.This article presents an update in the study of atmospheric depth prole using the value ofthe temperature at ground as characterization. The data used in the development becomesfrom balloon radiosonde launched in the site of the Pierre Auger Observatory between theperiod of August 2002 and December 2008.The note includes two variants in the modelization of the atmosphere as several layers:a rst and brief update increasing the number of layers considered, and a second studymodeling the variation of the temperature inside the layers.Both updates follow successfully the path of to characterize the variation observed in theatmospheric depth proles.
