Integrated Activities

We strive to strategically initiate, and support, cross-cutting projects. These projects bring together diverse teams of scientists from across the institute to help answer important questions.  Unlike scientific working groups, which have a more permanent status, and work within one of the institute's three departments, internal projects should bring together people from different departments, and have a limited lifetime.  Currently the institute supports three cross cutting projects, some in cooperation with partner institutes. In addition to the running internal projects listed below, past internal projects are described on the Project Archive page, and projects that are made possible through external funding are listed on the External Projects page.


The Coupled Model Intercomparison Project Phase 6 (CMIP6) is an international endeavour to better understand past, present and future climate changes. Referring to the Grand Science Challenges of the World Climate Research Programme (WCRP), CMIP6 aims to answer three broad questions:

(i) How does the Earth system respond to forcing?,

(ii) What are the origins and consequences of systematic model biases?, and

(iii) How can we assess future climate changes given climate variability, predictability and uncertainties in scenarios?

Jointly with the German weather service, the Max Planck Institute for Meteorology (MPI-M) develops the ICON modelling system for a broad range of applications. Within this framework, MPI-M develops and maintains the ICON Earth system model (ICON-ESM) and the large eddy resolving model (ICON-LEM).

Grand Ensemble

The Max Planck Institute for Meteorology (MPI-M) Grand Ensemble (MPI-GE) is the largest ensemble of a single state-of-the-art comprehensive climate model currently available.

The Grand Ensemble consists of five Large Ensembles of 100 simulations each under different forcing scenarios. This ensemble allows the separation of the forced signal from the model internal variability. It allows us to address questions that could not be answered in the past, such as:

Does internal variability change under different forcing conditions?

The Figure shows many possible realisations of the Earth under multiple scenarios.
