Resumen:
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 Malargüe and
averaged monthly models, the utility of the GDAS data is shown.
