Abstract. The atmospheric chemistry general circulation model ECHAM5/MESSy is combined with the Lagrangian transport scheme ATTILA and further developed towards a comprehensive representation of atmospheric chemistry related processes in the Lagrangian frame of reference. This includes the implementation of source, sink and transformation processes of atmospheric constituents. The Lagrangian representation provides a tremendous amount of additional information about spatio-temporal interrelations, which is not accessible from Eulerian models. Here, we apply the model system and newly developed diagnostic methods to investigate the impact of specific trace gas and air pollution source regions to the global chemical state of the atmosphere.
