We present a methodology to simulate the impact of the atmospheric models in
the background particle flux on ground detectors using the Global Data
Assimilation System. The methodology was within the ARTI simulation framework
developed by the Latin American Giant Observatory Collaboration. The ground
level secondary flux simulations were performed with a tropical climate at the
city of Bucaramanga, Colombia. To validate our methodology, we built monthly
profiles over Malarg”ue between 2006 and 2011, comparing the maximum
atmospheric depth, X$_mathrm{max}$, with those calculated with the Auger
atmospheric option in CORSIKA. The results show significant differences between
the predefined CORSIKA atmospheres and their corresponding Global Data
Assimilation System atmospheric profiles.
