...The main goals formulated in the initial phase of the collaboration were as follows: • better conservation properties than in the existing global models GME (Majewski et al., 2002) and ECHAM (Stevens et al., 2013), with the obligatory requirements of exact local mass conservation and mass-consistent tracer transport and the additional wish to achieve energy conservation; • better scalability on future massively parallel highperformance computing architectures; and • the availability of some means of static mesh refinement, which was subsequently concretized into the capability of mixing one-way nested and two-way nested grids within one model application, combined with an option for vertical nesting in order to allow the global grid to extend into the mesosphere (which greatly facilitates the assimilation of satellite data), whereas the nested domains extend only into the lower stratosphere in order to save computing time....

...Given changes in electronic publishing, such reports are becoming increasingly less accessible, and less acceptable, all the more so with the rise of coordinated projects such as the coupled model intercomparison project (presently phase 5, or CMIP5, Taylor et al.
