New atmospheric profiles for H.E.S.S. data analysis

Published online: 17 May 2017
Particles arriving to Earth allow us to scan and improve our understanding of the Universe, both in its composition and its dynamics. For ground-based experiments in astroparticle physics, the atmosphere plays a key role and its understanding, monitoring and modelling is essential for a realistic description in data analysis and simulations. In this work we present the development of a novel experimental atmospheric model, the GNNA120 model, describing the atmosphere above the H.E.S.S. gamma-ray observatory in Namibia. This new description is the most realistic to date and introduces the possibility to study variations at different time scales. This enables us to provide the first ever study of seasonal effects based on actual measured atmospheric profiles for the H.E.S.S. observatory and opens up the window to further improvements of the H.E.S.S. Monte Carlo simulations.
