The goal of this project is to improve our understanding of the Earth’s atmosphere and climate by means of numerical modelling. The Earth system is driven by several dynamical, chemical and radiative processes, which determine its composition and evolution and affect the global climate. The numerical representation of such processes is a difficult task and requires considerable computational resources, in order to properly simulate the different components of the system and their interactions with each other. In addition to the pure scientific interest, the growing societal concern for topics like the global climate change, the south-hemispheric ozone hole and the deterioration of air quality in metropolitan areas is further motivating the need for a deep understanding of these processes. The focus of this project is therefore twofold: on one side we aim at a better representation of the Earth atmosphere in a numerical model, on the other hand we will apply such model to quantify the impacts of human activities on the atmospheric composition and climate. We use a highly flexible numerical system, the ECHAM/MESSy Atmospheric Chemistry model, which allows using the same code for tackling different scientific problems. The model can be easily configured to set the horizontal and vertical resolution, the level of interaction between dynamics, chemistry and radiation, the complexity of the chemical reactions, as well as the parameters that describe the physical processes within the system. The use and application of the same code also facilitate the code development and documentation as well as the synergies between the users.
