RT Journal Article T1 Description of atmospheric conditions at the Pierre Auger Observatory using the Global Data Assimilation System (GDAS) A1 Arganda, E. A1 Arqueros Martínez, Fernando A1 García Pinto, Diego A1 Minaya Flores, Ignacio Andrés A1 Ortiz Ramis, Montserrat A1 Rosado Vélez, Jaime AB Atmospheric conditions at the site of a cosmic ray observatory must be known for reconstructing observed extensive air showers. The Global Data Assimilation System (GDAS) is a global atmospheric model predicated on meteorological measurements and numerical weather predictions. GDAS provides altitude-dependent profiles of the main state variables of the atmosphere like temperature, pressure, and humidity. The original data and their application to the air shower reconstruction of the Pierre Auger Observatory are described. By comparisons with radiosonde and weather station measurements obtained on-site in Malargue and averaged monthly models, the utility of the GDAS data is shown. (C) 2012 Elsevier B.V.
