Central IT Services
IT services are provided at MPI-M by the Central IT Services (CIS) group.
The most important services of the Central IT Services are:
- Procurement, setup and management of IT hardware and software for both users (laptops, PCs) and infrastructure (servers, networks, etc.)
- Central user administration
- Provision of an efficient network (LAN, WLAN)
- Central IT help desk as a contact point for all IT-related issues
- Provision of services to support daily work (e.g. version management, project management, websites, etc.)
- Ensuring secure IT operations (failover, backup, IT security)
Detailed documentation on the IT Group’s offerings can be found in the Wiki of the institute.
An account (username and password) is required to use most IT services. Usually, an account will be created for you as soon as you have a contract with MPI-M. If you are a guest at MPI-M and need an account, your group leader at MPI can request an account for you. Further details are described in the institutes Wiki.
If you have any questions or problems using the IT systems at MPI-M, please contact the IT help desk.
Please note that questions regarding the DKRZ systems (e.g. Levante or data archive) will be answered by the DKRZ user support.

Towards resolving internal tides in the ocean
Internal tides are the most energetic internal waves in the ocean interior. In the open ocean, they are generated when tides flow over ridges and sea mounts at the sea floor. Internal tides play a crucial role in shaping the ocean's internal wave field through wave-wave and other non-linear interactions. These processes allow wave energy to be transferred to turbulent motions, enabling the dissipation of energy necessary to balance the continuous power input at the sea surface. Thus, internal tides are crucial for establishing energy pathways in the ocean. On the way toward resolving internal tides, we need to make sure that the open ocean tides are realistically simulated.
Based on a suite of tidal experiments and using the observation-constrained tides from TPXO9 (Egbert et al. 1994, Egbert and Erofeeva, 2002), the colleagues in the Climate Variability department at the Max Planck Institute for Meteorology found that the ocean component of ICON is capable of producing the main features of the open-ocean tides as described by the geographical distributions of amplitude, phase, and amphidromic points. They show that using a spatially inhomogeneous grid does not deteriorate the quality of the simulated tides, an issue relevant for using the ocean component of ICON in its telescoping configuration. This telescoping configuration facilitates a global kilometer-scale grid with a locally refined ocean grid. The authors show further that implementing a parameterization of topographic wave drag improves the quality of the simulated tides in deep oceans independent of model configurations used, and the implementation of the parameterization of the self-attraction and loading effect in high-resolution (10 km) of the ocean component of ICON improves the quality of tides in the deep ocean. Finally, they show that the quality of tides simulated is sensitive to the time step or the parameters in the time stepping scheme used for obtaining the model solution.
