About Participating ICNWG Organizations | International Network Working Group

» Diagram showing the overlap between the ESGF program and the EYR-Global Program. Data centers noted in the crossover region are supported by the EYR-Global network organizations (on the far right). ESGF has many more institutions that participate in their program; however, five data centers are pioneering how to upgrade or update their infrastructures to improve large-scale data replications.

About the ESGF Sites

Participating centers host ESGF data replication nodes that serve data to the international climate community.


Over the past two decades, the Lawrence Livermore National Laboratory's (LLNL) Analytics, Informatics, and Management Systems (AIMS) project has enabled the scientific climate community to self-organize and build an information infrastructure that has revolutionized how climate modeling and intercomparison are performed. The AIMS program leads collaborations to develop an uncertainty quantification diagnostic test bed and data infrastructure for the DOE Accelerated Climate Modeling for Energy (ACME) project. Moreover, by working with many others in a global setting, the team is resolving many of the technical challenges regarding scaling and federation (e.g., authentication, sharing, location of data and processing resources, interface standards, etc.) issues that face any attempted large-scale information system. This has been accomplished by using an open systems approach that leverages the efforts of a global community. The technical motivation for this program is based on the success of the Earth System Grid Federation (ESGF) and the Ultra-scale Visualization Climate Data Analysis Tools (UV-CDAT).

The Centre for Environmental Data Archival (CEDA) serves the environmental science community through four data centers, data analysis environments, and participation in a host of relevant research projects. CEDA aims to support environmental science, further environmental data archival practices, and develop and deploy new technologies to enhance access to data.

Based within the RAL Space department of the Science and Technology Facilities Council's Rutherford Appleton Laboratory, CEDA hosts a range of activities associated with environmental data archives. These activities include running a number of key environmental data centres for the environmental research community as well as being in the vanguard of the development of data archival and delivery practices and technologies.

DKRZ, the German Climate Computing Centre, provides the tools and the associated services which are needed to investigate the processes in the climate system: computer power, data management, and guidance to use these tools efficiently. As a national service provider, DKRZ operates a supercomputer center to enable climate simulation and provides the scientific users with the technical infrastructure needed for the processing and analysis of climate data. This also includes support for related application software, and advice and support in data processing issues. Finally, DKRZ also participates in national and international joint projects with the aim of improving the infrastructure for climate modeling. DKRZ thus constitutes an outstanding research infrastructure for model-based simulations of global climate change and its regional effects. This mission is consistent with the new High-Tech Strategy for climate protection as presented by Prof. Dr. Annette Schavan, Federal Minister for Education and Research, at the second Climate Research Summit in Berlin in October 2007.

The Royal Netherlands Meteorological Institute (KNMI) maintains global climate models of intermediate complexity and develops a state-of-the-art earth system model (EC-EARTH) as research tool and as tool for developing climate scenario’s. KNMI is internationally recognized in the fields of climate extremes, thermohaline circulation, tropical variability, atmospheric dynamics and land processes. In preparation for CMIP6, as contribution to the ESGF and as provider of the climate4impact.eu portal KNMI is preparing an ESGF data node. The Climate4impact portal, built on the firm ESGF foundation, is the result of a collaborative effort within the European FP-7 project IS-ENES ; an effort directed to Bridging Climate Research Data and the Needs of the Impact Community (climate change impact modellers, impact and adaptation consultants, as well as other experts using climate change data). The portal provides data transformation tooling for tailoring data and mapping & plotting capabilities. Also guidance on how to use climate scenarios, documentation on the climate system and examples in several impact and adaptation themes are presented and described, along with the steps required to go from GCM data to impact model input data.

About the Networks

Participating networks provide the national wide-area network connectivity for an ESGF replication node. Please see the ICNWG network diagram for more detailed information about the ESGF nodes' interconnectivity.

» AARNet

AARNet, Australia’s Academic and Research Network, interconnects Australian universities and Commonwealth Scientific and Industrial Research Organisation (CSIRO), and other organisations with a research and education mission, or with whom the education and research sector interacts (including hospitals, vocational training providers, schools and museums). AARNet, connecting over one million users at institutions, is a national research and education network that provides unique information communications technology capabilities to enable Australian education and research institutions to collaborate with each other and their international peer communities.


DFN, the German national research and education network, is the communications network for science and research in Germany. It connects universities and research institutions with one another and has become an integral part of the European and worldwide community of research and education networks. DFN is organized by the non-profit association, DFN-Verein.
