The Alfred Wegener Institute - Helmholtz Centre for Polar and Marine Research (AWI) carries out research in the Arctic and Antarctic as well as in the high and mid latitude oceans. The institute coordinates German polar research and makes available to national and international science important infrastructure, e.g. the research icebreaker “Polarstern” and research stations in the Arctic and Antarctic. The AWI is shareholder and user of DKRZ.


The Climate Service Center Germany, or short GERICS, offers products, advisory services and decision-relevant knowledge based on sound scientific knowledge in order to support government, administration and business in their efforts to adapt to climate change.

In 2009, the Cluster of Excellence CliSAP gave the impetus for the creation of a climate research network in Hamburg. The initial partners were soon joined by further institutes, such as the German Weather Service and Federal Maritime and Hydrographic Agency, marking the birth of the KlimaCampus Hamburg. Here, experts collaborate on various aspects of climate, climate change and its impacts, e.g. in joint projects like the ongoing KlimaCampus Colloquium.

The Max-Planck Institute for Biogeochemistry contributes to the understanding of how living organisms – including humans - exchange fundamental resources like water, carbon, nitrogen and energy with their environment, and how this affects and responds to global climate and environmental change. For its modelling activities the institute uses DKRZ's facilities.


Current research at the Max Planck Institute for Chemistry in Mainz aims at an integral understanding of chemical processes in the Earth system, particularly in the atmosphere and biosphere. For its modelling activities the institute uses DKRZ's facilities.

The Institute of Atmospheric Physics investigates the physics and chemistry of the global atmosphere from the Earth's surface up to the upper boundary of the middle atmosphere at about 120 km height. The resulting data are quite important for climate models. For its own climate modelling activities the institute also uses DKRZ's facilities.

FU Berlin Logo

Among other areas, the research Institute of Meteorology at the Freie Universität Berlin (FU Berlin) focuses on interactions in the climate system.


The GEOMAR Helmholtz Centre for Ocean Research Kiel is one of the world’s leading institutes in the field of marine sciences. The institute investigates the chemical, physical, biological and geological processes of the seafloor, oceans and ocean margins and their interactions with the atmosphere.


TheGerman Climate Consortium (Deutsches Klima-Konsortium e.V. - DKK) represents the essential parts of German climate and climate impact research. Under the guiding principle “Research for Society, Economy and the Environment”, DKK brings together twenty-one internationally renowned research organizations, amongst them DKRZ. These organizations make an important contribution to recognize and respond to climate change and climate impacts.

LOGO:ENES (neu, GIF, 128x47)

In 2001, a large number of European climate modeling groups joined to form the European Network for Earth System Modeling (ENES) with the aim of accelerating the development of Earth system models for climate through the exchange of model software and results and improving high performance computing facilities. Four European projects initiated by ENES are ongoing: COMBINE, METAFOR, EUCLIPSE and IS-ENES. DKRZ contributes to METAFOR, EUCLIPSE and IS-ENES. The ENES newsletter, published on a quarterly base, aims to keep interested parties up-to-date with the latest news regarding the activities of the ENES community.


The ICON model, which is jointly developed by the Max Planck Institute for Meteorology (MPI-M) and the German Meteorological service (DWD), will serve as the basis for numerous future research projects and simulations. DKRZ is involved in development activities in several areas (i.a. software engineering, model coupling, program optimization and visualization).


The European Centre for Medium-Range Weather Forecasts (ECMWF) Forecasts is an important partner for DKRZ in various infrastructure projects and also a provider of important data sets such as the ERA5 reanalysis data.


The Klimanavigator is a German knowledge portal of climate research and adaptation initiatives. More than 60 German institutes - including DKRZ - are represented in this portal, which intends to collect and serve information at a level that also non-specialists can easily understand.

Informatics / High Performance Computing / Research Data Infrastructures


In 2012 the University of Hamburg conjointly with the DKRZ, the Max Planck Institute for Meteorology, the excellence cluster CLISAP and the Technical University Harburg founded the Lothar Collatz School for Computing in Science, which promotes computational education and research at the interface of Mathematics, Computer Science and Computational Sciences.


The Gauß-Allianz for supercomputing is a cooperation of the leading German high performance computing centers – among them DKRZ. It establishes the requirements for a sustainable and efficient use of supercomputing resources, coordinates the HPC related activities of its members and implements the BMBF study “HPC in Germany – Reasons for a Strategic Alliance”.

The IPCC Data Distribution Centre (IPCC DDC) supports the work of the IPCC through data management in accordance with the FAIR Guidelines. Through various data services, the DDC provides relevant climate change data to  the IPCC authors. At the end of each reporting cycle, the DDC makes these underlying data for the IPCC reports available to further data users. The DDC is jointly managed by DKRZ and currently 3 other international DDC partners. The DDC is overseen by IPCC TG-Data.
