The Max Planck Institute for Meteorology (MPI-M) is an internationally renowned institute for climate research. Its mission is to understand Earth's changing climate.


The MPI-M comprises three departments and, together with the Opens external link in current windowUniversity of Hamburg, an international PhD program:

The Atmosphere in the Earth System

The Land in the Earth System
The Ocean in the Earth System


In addition the institute hosts independent research groups focused on the following topics:


Scientists at the MPI-M investigate what determines the sensitivity of the Earth system to perturbations such as the changing composition of its atmosphere, and work toward establishing the sources and limits of predictability within the Earth system. MPI-M develops and analyses sophisticated models of the Earth system, which simulate the processes within atmosphere, land and ocean. Such models have developed into important tools for understanding the behaviour of our climate, and they form the basis for international assessments of climate change. Targeted in-situ measurements and satellite observations complement the model simulations.


Together with several other non-university research institutions the MPI-M and the University of Hamburg constitute Opens external link in current windowCliSAP, a centre of excellence for climate research and education in Hamburg, Germany.

Focus on

Clouds and Precipitation in the Climate System – HD(CP)2: The 100 Meter Bet

Clouds and Precipitation play a major role in answering the question, how climate will change under human influence. The lack of understanding of physical processes and too little computer capacity is demonstrably one of the largest problems for uncertainty in current climate models.

"High Definition Clouds and Precipitation for advancing Climate Prediction (HD(CP)2" is an initiative funded by the German Federal Ministry for Education and Research (BMBF). It addresses this cloud-precipitation problem and leverages both the rapid developments in simulation and measurement science. The project is led by Prof Bjorn Stevens, Managing Director of the Max Planck Institute for Meteorology (MPI-M) and head of department "The Atmosphere in the Earth System", and coordinated by Dr Florian Rauser.
