In this paper we investigate the energy footprint and performance profiling of COSMO-ART on various HPC platforms. This model is an extension of the operational weather forecast model of the German weather service (DWD), developed for the evaluation of the interactions of reactive gases and aerosol particles with the state of atmosphere at the regional scale. Different measurement devices and energy-aware techniques are described to evaluate both time and energy to solution of the considered application and to gain detailed insights into power and performance requirements. Our motivation is to improve corresponding code sections to sustain performance while minimizing energy-to-solution. This preliminary work sets the basis for subsequent studies to tackle challenges related to energy efficient high performance computing in the framework of the Exa2Green project (EU FET Project, http://exa2green.eu/).
